Question

cellular respiration is going on right now in virtually every cell in your body, as well as in the cells of most organisms on the planet. in humans and many other species, the process can be broken into five major stages: glycolysis → pyruvate processing → citric acid cycle → electron transport chain (etc) → atp synthase lets start with the first three: • glycolysis is a sequence of ten enzyme - catalyzed reactions that begins with glucose as a reactant and ends with two 3 - carbon molecules called pyruvate as products. • pyruvate processing occurs in a single, multi - unit enzyme complex. it starts with pyruvate and produces molecules called acetyl coenzyme a (acetyl - coa). • the citric acid cycle is a sequence of nine enzyme - catalyzed reactions that begins with acetyl - coa and completes the oxidation of glucose. based on this information, which diagram best represents the inputs and outputs of glycolysis, pyruvate processing, and the citric acid cycle? glucose pyruvate acetyl - coa glycolysis pyruvate processing citric acid cycle glucose pyruvate acetyl - coa glycolysis pyruvate processing citric acid cycle glucose co₂ co₂ glycolysis pyruvate processing citric acid cycle

Explanation:

• Glycolysis: Input is glucose, output is pyruvate.
• Pyruvate processing: Input is pyruvate, output is acetyl - CoA.
• Citric acid cycle: Input is acetyl - CoA.

Answer:

The first diagram (where glucose is input for glycolysis, pyruvate is input for pyruvate processing, and acetyl - CoA is input for citric acid cycle) is correct.
