Question

making models: drawing flow charts--cellular respiration
5 parts | 0.33 of 1 point
maria has drawn a flow chart using stars to track electron carriers (nadh and fadh₂) during cellular respiration, but she hasnt completed her model. if twelve electron carriers are delivered to the electron transport chain (etc) per molecule of glucose, how many stars should she show being produced during glycolysis and pyruvate processing?
etc
glucose → pyruvate → acetyl coa
co₂
co₂
0 stars + 4 stars
2 stars + 2 stars
4 stars + 0 stars
no more stars

Explanation:

Step1: Recall electron - carrier production in glycolysis

In glycolysis, for each molecule of glucose, 2 NADH (electron carriers) are produced. So, 2 stars should be shown for glycolysis.

Step2: Recall electron - carrier production in pyruvate processing

In pyruvate processing, 2 pyruvate molecules are converted to 2 acetyl - CoA. For each pyruvate molecule converted to acetyl - CoA, 1 NADH is produced. So, for 2 pyruvate molecules, 2 NADH are produced, which means 2 stars for pyruvate processing.

Answer:

2 stars + 2 stars
