Question

3 multiple choice 2 points in which stage of aerobic respiration can up to 34 atps be made? krebs cycle glycolysis fermentation electron transport chain 4 multiple choice 2 points what is the function of ribosomes in prokaryotic cells? regulate the flow of substances into and out of the cell protein synthesis reproduction support and protection 5 multiple choice 2 points what is the main function of nadh and fadh2 in the krebs cycle? to synthesize lipids to transfer high - energy electrons to generate atp to regulate enzyme activity

Explanation:

• For question 3: The electron - transport chain in aerobic respiration can produce up to 34 ATPs through oxidative phosphorylation.
• For question 4: Ribosomes in prokaryotic cells are responsible for protein synthesis, translating mRNA into proteins.
• For question 5: In the Krebs cycle, NADH and FADH2 transfer high - energy electrons to the electron - transport chain.

Answer:

1. D. Electron Transport Chain
2. B. protein synthesis
3. B. To transfer high - energy electrons
