Question

question 79

__ is the energy - releasing process or step that is found in all organisms and occurs in the cytoplasm of eukaryotic

a the citric acid cycle

b the electron transport system

c glycolysis

d photosynthesis

question 80

this stage of aerobic respiration occurs in the cytoplasm.

a glycolysis

b photosynthesis

c the citric acid cycle

d electron transport

e fermentation

Explanation:

• Question 79:
• Glycolysis is a universal energy - releasing process. It occurs in the cytoplasm of all organisms (both prokaryotes and eukaryotes). The citric acid cycle occurs in the mitochondria of eukaryotes. The electron transport system is also located in the mitochondria (in eukaryotes) or the cell membrane (in prokaryotes). Photosynthesis is not an energy - releasing process in the sense of cellular respiration; it is an energy - capturing process (in plants and some other organisms).
• Question 80:
• Glycolysis is the first stage of aerobic respiration and occurs in the cytoplasm. Photosynthesis is not a stage of aerobic respiration. The citric acid cycle occurs in the mitochondrial matrix. The electron transport chain occurs in the inner mitochondrial membrane. Fermentation is an anaerobic process, not a stage of aerobic respiration.

Answer:

• Question 79: C. Glycolysis
• Question 80: A. glycolysis
