The active site of an enzyme is _____________. Group of answer choices the region of an enzyme that attaches to the product the region of a product that detaches from the enzyme the region of a substrate that is changed by an enzyme the region of an enzyme that attaches to a substrate the highly changeable portion of an enzyme that adapts to fit the substrates of various reactions

Answers

Answer 1

Answer: The correct option is (the region of an enzyme that attaches to a substrate).

Explanation:

The anabolic and catabolic processes in a cell are directed and regulated by enzymes. An enzyme has the ability to speed up a metabolic reaction by lowering the amount of energy needed to start the reaction. Without enzymes, these processes would be extremely slow. They also arrange the reacting molecules in a manner that will cause the chemical change to take place rapidly. It does so through the following steps:

--> molecules of substrate combine with the enzyme at its active site.

--> the substrate molecules combine with enzyme molecules for a short time, forming an enzyme-substrate complex.

--> New substance ( product) is formed which leaves the active site of the enzyme thereby making it free for another reaction to take place.

In conclusion, the ACTIVE SITE of an enzyme is the region of an enzyme that attaches to a substrate allowing chemical reaction to take place.

A population of birds can have large, heavy beaks or thin, long beaks.

What can we say based on this data?
Select one:

We cannot conclude anything without having more data.

Having heavier beaks is a survival advantage.


Having longer beaks is a slight survival advantage, but having more data would help to confirm.
undo

There is no survival advantage between having heavier beaks and longer beaks.

Answers

Answer:

We cannot conclude anything without having more data.

Explanation:

All the statement says it that the birds have different types of beaks. There is no mention of information that the beak difference brings advantage or not. If the question were to say the heavy beaks survive more, then the answer would be those birds have an advantage- because it does not, the answer is we need more data

Determine whether the following statement is true or false. If false, select the choice that will make it true. "Aerobic respiration produces Glucose."


A. True
B. False, it produces proteins.
C. False, it breaks ATP into ADP.
D. False, it produces ATP.

Answers

Answer:

D. False, it produces ATP

The statement "Aerobic respiration produces Glucose" is false. This is because it produces ATP. Thus, the correct option is D.

What is Aerobic respiration?

Aerobic respiration may be defined as a chemical process in which oxygen is utilized in order to construct energy from carbon dioxide and water. This type of respiration typically takes place in the presence of oxygen to catalyze a given set of reactions.

Aerobic respiration occurs in presence of water. It takes place with help of glucose further convert into pyruvate to derive carbon dioxide, water, and energy in form of ATP. The process of aerobic respiration is also known as oxidative metabolism and cell respiration. In this process, glucose reacts with oxygen to form ATP.

Therefore, the statement "Aerobic respiration produces Glucose" is false. This is because it produces ATP along with carbon dioxide and water. Thus, the correct option is D.

Explanation:

Sarcopterygii also known as lobe-finned fishes which usually possess a choana, paired fins with a fleshy base over a bony skeleton, persisting notochord, 2 dorsal fins and nares are present internally. The lungfishes are considered the closest living relatives of tetrapods because of the presence of some common features. The African lungfish has epithelial crypts located at the base of the lamellae of the olfactory epithelium that express markers of the vomeronasal receptors in tetrapods.

(a)The strength of natural fibers is very less as compared to synthetic fibers.  Natural fibers are heavy in weight.  Natural fibers can be damaged by moths and other insects.  These fibers are not wrinkle-free.  These fibers are not long lasting and hence not durable.

(b)  Cellulose is termed as polymer because it is made up of many monomer units.

(c) Rayon is first man- made fibre it is known as artificial silk because it have properties that are similar to silk.

(d) Rayon possesses many properties of natural fibers since it is a semi-synthetic fiber. Nylon is a synthetic fiber and has properties that are completely different from natural fibers. The key difference between rayon and nylon is their resistance to wrinkles and tears.

(e) Nylon has since become a popular choice, as it has excellent wind resistance, good elasticity, mildew resistance, and is comparatively cheaper. The material is also lightweight and dries quickly.

(f) When the piece of cotton is burnt then it burns completely and produces no odour or smell. When nylon is burnt, It completely burns and produces burning paper like odour. When nylon is burnt then the nylon is completely shrink and starts to melt first and then produces odour during the time of burning

Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself

Centrioles play a role in organizing microtubules that serve as the cell's skeletal system. They help determine the locations of the nucleus and other organelles within the cell.

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.
