From the following which is true about cellular respiration (select all that apply)
1. In prokaryotes, the electrons transport is in the plasma membrane
2. Prokaryotic fermentation net yield is 4 ATP and oxidative respiration has 32 ATP
3. The major regulatory enzyme of glycolysis is Hexokinase
4. Substrate-level phosphorylation is catalyzed by kinase and transfers the phosphate group from an intermediate in a metabolic pathway directly to a molecule of ADP
Homework Answers
Statements 1 and 4 are true. Electron transport chain of prokaryotes is operated in plasma membrane as they do not have mitochondria. Pyruvate kinase catalyzes substrate level phosphorylation, a high energy phosphate group is directly transferred from an intermediate to ADP and ATP is produced.
Net yield in prokaryotic fermentation is 2 ATP per glucose molecule, that is why statement 2 is false. Major regulatory enzyme in glycolysis is phosphofructokinase, that is why statement 3 is false. Though phosphofructokinase is not the only one, hexokinase catalyzes the initial step of glycolysis.
