Which of the following is true regarding glycolysis ?
Choose 1 answer.
A.) It requires glucose as a reactant.
B.) It produces 36 ATP.
C.) It occurs in the mitochondria.
D.) It is an aerobic process. ​

Answers

Answer:

I would have to say A

Explanation:

Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. So we already know that it uses glucose because thats what its breaking down. Glycosis produces 2 ATP so B is wrong. Glycolysis happens in the cytoplasm so C is wrong. Finnaly aerobic is using free oxygen in the process of the reaction. However glycolysis uses no oxygen and is  anaerobic.

Glycolysis requires glucose as a reactant.  

Glycolysis refers to a cytoplasmic pathway that dissociates glucose into the three-carbon compound and produces energy in the form of ATP.  

• The process of glycolysis takes place in the cytoplasm.  

• In the process, the net production of 2 ATPs takes place.  

• It can be both anaerobic and aerobic process.  

• The process of glycolysis completes in 10 steps, five of which are in the preparatory phase and the rest 5 are in the pay-off phase.  

• The process of glycolysis is used by all the cells of the body to produce energy, and the final product of glycolysis is pyruvate.  

Thus, correct answer is option A, that is, it requires glucose as a reactant.

Products enter a reaction and reactants come out of a reaction true or false?

Answers

Answer:

[tex]\boxed {\boxed {\sf False }}[/tex]

Explanation:

In a chemical reaction, the products are produced. The reactants are the substances that react.

In a chemical reaction equation (with the arrow pointing right) the reactants are on the left and the products on the right.

[tex]reactants \rightarrow products[/tex]

The reactants enter and the products come out.

So, the statement given - products enter a reaction and reactants come out - is false and it is actually the other way around.

These structures suggest that Dogs and humans are more closely related than snakes and humans.

Does snake have backbone?

Yes, snakes have a backbone. The backbone is made up of a series of bones called vertebrae, which are connected by ligaments and muscles. The vertebrae of a snake are unique because they are loosely connected, allowing the snake to move and bend in a wide variety of directions.

Dogs and humans are more closely related than snakes and humans because they both have vertebral columns, tails, and limbs while snakes only have a vertebral column and a tail. This suggests that a common ancestor shared these features with both dogs and humans, while the common ancestor of snakes did not possess these features.

Therefore, Dogs and humans are more closely related than snakes and humans is the correct answer.

Dogs, snakes, and humans share a common ancestor. The presence of a vertebral column in all three organisms suggests that they belong to the same group of vertebrates,

So the correct answer is D.  Dogs, snakes, and humans share a common ancestor.

What is a common ancestor?

A common ancestor is a hypothetical organism that is ancestral to two or more different groups of organisms. In other words, a common ancestor is an organism that gave rise to two or more distinct lineages through evolutionary divergence. All organisms that share a common ancestor are said to be related, and their evolutionary relationships can be represented as a branching tree-like diagram called a phylogenetic tree. The concept of a common ancestor is fundamental to evolutionary biology, as it allows scientists to infer the evolutionary history and relationships between different groups of organisms.

Dogs, snakes, and humans share a common ancestor. The presence of a vertebral column in all three organisms suggests that they belong to the same group of vertebrates, but differences in tails and limbs suggest that their ancestors underwent evolutionary changes that led to these differences.

Therefore, options A and C are partially correct but do not capture the full picture, while option B is incorrect. The correct answer is D.
