NADH and FADH2 are necessities in the electron transport chain because they power the chain by moving electrons into it.
NADH and FADH2 are both generated at the initial stages of respiration (the Kreb's cycle), a process during which food materials are broken down to generate energy. NADH is generated from NAD+ as a result of the addition of electrons while FADH2 is generated from FAD also due to the addition of electrons.
Once generated, both compounds get transferred into the innermost membrane of the mitochondrion where they travel down the electron transport chain, donating their electrons in the process and creating an electrochemical gradient to generate ATP.
Without NADH and FADH2, there will not be electrons to power the electron transport chain and the generation of ATP would become impossible.

The correct answer is They move electrons to the electron transport chain.

2) ¿Cuál de los siguientes hechos no es una evidencia de una reacción química? a) Presencia de un catalizador b) Cambio de color d) Liberación de gas
Answer:
a) Presencia de un catalizador
Explanation:
Los dos tipos de cambios que experimentan las sustancias en la química son cambios químicos y físicos.
Un cambio físico es un cambio es un cambio en el que la sustancia cambia en su apariencia o su forma de una manera que es reversible y en la que no se forma una nueva sustancia.
Un cambio químico es aquel en el que hay un cambio en las sustancias presentes y se forma una nueva sustancia.
La evidencia de que ha tenido lugar un cambio químico incluye
1) La formación de un precipitado a partir de la mezcla de sustancias.
2) Un cambio en el color de las sustancias.
3) Un cambio en el olfato (que desprende un olor) o en el sabor.
4) La sustancia produce luz (brilla)
5) El volumen total cambia
6) Cambio de temperatura (la mezcla se calienta o enfría)
Por lo tanto, la presencia de un catalizador, que es una sustancia que no participa en una reacción pero aumenta la velocidad de reacción, no es evidencia de una reacción química.
Match the following STDs with their descriptions. 1. can cause sores, rashes, dementia, or blindness gonorrhea 2. can cause burning urination and infertility chlamydia 3. similar to gonorrhea but more likely to be carried unknowingly syphilis 4. parasitic STD causing genital irritation and mild discharge 5 crabs 5. pubic lice that cause itching trichomoniasis 6. untreatable STD causing periodic outbreaks of blisters 1 HPV 7. can cause genital warts or cervical cancer 6 genital herpes
Answer:
1. Syphilis
2. Gonorrhea
3. Chlamydia
4. Trichomoniasis
5. Crabs
6. Genital herpes
7. HPV
Explanation:
STD is an acronym for sexually transmitted disease and it can be defined as diseases that are easily transmissible or contractable from another person through sexual intercourse. Thus, STD spread from an infected person to an uninfected person while engaging in unprotected sexual intercourse. Some examples of STDs are gonorrhea, chlamydia, syphilis, HIV, HPV, etc.
Generally, contracting STDs has a detrimental effect to a patient because it causes an opening (break) or sore in the body of the carrier (patient) and as such making them vulnerable to diseases that are spread through bodily fluids e.g human immunodeficiency virus (HIV), Hepatitis, staphylococcus, AIDS, etc.
1. Syphilis: can cause sores, rashes, dementia, or blindness.
2. Gonorrhea: can cause burning urination and infertility
3. Chlamydia: similar to gonorrhea but more likely to be carried unknowingly
4. Trichomoniasis: parasitic STD causing genital irritation and mild discharge.
5. Crabs: pubic lice that cause itching.
6. Genital herpes: untreatable STD causing periodic outbreaks of blisters
7. HPV: can cause genital warts or cervical cancer. HPV is an abbreviation for human papillomavirus and it's a virus that causes most common sexually transmitted infection, giving rise to skin or mucous membrane growths (warts).
Answer:
1) syphilis
2) gonorrhea
3) chlamydia
4) trichomoniasis
5) crabs
6) genital herpes
7) HPV
The following illustration shows a food web for a kelp forest off of the coast of California. What do you predict would happen to the kelp population if the sea otter population declined?
The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
The kelp population would increase: sea otters eat urchins, but not exclusively.
The kelp population would remain unchanged; sea otters do not eat the kelp.
The kelp population would remain unchanged: sea otters eat urchins, but not exclusively.
Answer:
The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
Explanation:
The diagrammatic illustration in this question is showing a food web made up of a variety of species feeding on one another. As shown in the food web, sea otters are one of the top predators that can eat a wide variety of organisms.
Sea urchins feed directly on kelp, however, the population of sea urchins can be controlled by sea otters which feed on sea urchins. Hence, if population of sea otters declined, more sea urchins will be available to feed on the kelp population, hence, will DECREASE.
Answer:The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
Because the otter population decreases the urchin population increases and therefore the demand for kelp increases and the kelp population will decrease as the population of urchins increases and it feeds on the kelp and due to the reduction in otters there is nothing controlling the urchin population

The term bycatch or incidental catch refers to ________. non-target species that are caught along with commercial species species harvested for industrial purposes species raised in aquaculture settings species caught as part of traditional fisheries krill and other shellfish
Answer:
The correct answer is ''non-target species that are caught along with commercial species''
Explanation:
Bycatch refers to bycatch organisms that are not targeted by the fishery. Occurs inadvertently in fishing gear, all fisheries have some unwanted bycatch. Species with little or no commercial value, juvenile stages, or discarded gravid females of the target species (s) are generally included here. These incidental catches can be marginal when fishing is carried out with selective or very substantial gear, when the gear used indiscriminately catches everything that comes along its route. In marine fisheries, it causes injury or death to mammals, birds, turtles, fish, elasmobranchs, and invertebrates.
1）Fishing boats have decreased the number of herring in the sea. Explain why that could affect the number of offspring puffins can raise.
2） Which animals have a bigger food supply now there are fewer herrings?
3） Global warming is expected to reduce the biomass of phytoplankton in the oceans. What effect will that have on the rest of the food web?
Explanation:
1) When the number of herrings decrease, the food available for the puffins decrease and therefore they will not be able to feed their offspring. This will cause the number of offspring to decrease.
2) Any other animal(s) which hunts and eats the same prey as a herring will now have a bigger food supply.
3) When the biomass of phytoplankton decrease, the next animal in the food web will not have any food and their numbers will decrease, decreasing the number of the animals next in the web, as they too lose their food. This will continue for the rest of the food web and the number of animals will decrease.

In a separate maddyase experiment using (Et)-10nM, the reaction velocity is measured as 3uMS. What is the substrate concentration used in the experiment
Answer: hello your question has some missing data attached below is the missing data
Applying the Michaelis-Menten Equation
An enzyme is found that catalyzes the reaction X ⇋ Y Researchers find that kcat for this enzyme is 600s^-1 and carry out several additional experiments.
answer :
substrate concentration [ x ] = 10⁻⁵ M
Explanation:
Given data:
[Et ] = 10 * 10⁻⁹ M ,
Reaction velocity ( V₀ ) = 3* 10⁻⁶ Ms⁻¹
applying Michaelis-Menten Equation
= 3* 10⁻⁶ = [tex]\frac{600 *10*10^{-9} * (X) }{10^{-5} + (X) }[/tex] ,
= ( 3 * 10⁻⁶ )( x ) + ( 3 * 10⁻¹¹ ) = ( 6 * 10⁻⁶ ) ( x )
hence the substrate concentration [ x ] = 10⁻⁵ M

How do simple organisms exchange substances?
Answer:
A simple, unicellular organism (consisting of one cell) can rely on diffusion to move substances into and out of the cell. Its surface area is large compared to its volume , so nutrients and other substances can pass quickly through the membrane and around its 'body'.
