During glycolysis, glucose is broken down into two molecules of pyruvate.

mojhsa [17]

Answer:

Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose.

Explanation:

Glycolysis is an oxidation reaction in which glucose reacts with oxygen molecules and oxidized. By oxidizing glucose, it produces pyruvate, adenosine triphosphate (ATP) and nicotinamide adenine dinucleotides (NADH). Glycolysis has two phases. In the first phase, 2 ATP molecules are invested for the phosphorylation of glucose to break down into a simpler one. In the second phase of glycolysis, 4 ATP molecules are earned back with 2 NADH and a simpler form of glucose (6C) to pyruvate (3C) by oxidizing glucose.

A model is a representation, substitute, or simplification of what is being studied, but it is also similar to what it represent

Georgia [21]

Answer:

The correct option is b. the model is insufficiently labeled

Explanation:

Models showing certain cycles should clearly show the reactants and the products being formed. They should be able to depict the various changes in the reactants which lead to the formation of the products.

The diagram shown in the picture is a poor depiction for the process of photosynthesis as well as cellular respiration. I does not tell us the products being formed. Like oxygen gas is released during photosynthesis but it is just labelled as gas in the diagram. The sugar being formed is also not named which is glucose.
