Which stage of cell respiration produces co2:
a. glycolysis
b. fermentation
c. citric acid cycle
d. electron transport chain

C : Citric acid Cycle

Explanation: Cell respiration or Cellular respiration is term by which food energy is converted into the usable energy source Adenosin triphosphate ( ATP ). Cell respiration is a set of metabolic reactions , processess and pathways.

Citric acid cycle is set of reactions by which maximum amount of CO2 is released. In Citric acid cycle acetyl CoA undergoes releactions in presence of necessary enzymes by which CO2 is released .

in 1972 the fluid—mosaic membrane model of membrane structure was proposed based on thermodynamic principals of organization of membrane lipids and proteins and available evidence of asymmetry and lateral mobility within the membrane matrix [s. j. singer and g. l. nicolson, science 175 (1972) 720–731].

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.
