Solutions

Expert Solution

Answere :

Question 1 : The correct option is "oxidised".

During cellular respiration, glucose is oxidised. Glucose undergo oxidation because it loses hydrogen.

Question 2 : The correct option is "reduced".

During cellular respiration, oxygen is reduced. Oxygen accept electron and hydrogen, so it undergo reduction in cellular respiration.

Question 3 : The correct option is "glycolysis".

Glycolysis is the breakdown of glucose into two molecules of pyruvate.Glycolysis occur in cytoplasm.

Question 4 : The correct option is "electron transport chain".

The electron transport chain is a series of carriers on the cristae of the mitochondria and extracts energy from NADH and FADH2 to produce molecules of ATP.

Question 5 : The correct option is "citric acid cycle".

The citric acid cycle occurs in the matrix of the mitochondria and produces NADH and FADH2.

Citric acid cycle or Kreb cycle is a process in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions. It occur in matrix of mitochondria.

6. Glucose is completely oxidized to carbon dioxide with the concomitant production of several reduced electron carrier molecules. Oxidative phosphorylation ensures the regeneration of these electron carrier molecules. A. Cell Y is able to carry out glycolysis, citric acid cycle, and oxidative phosphorylation. However, a certain mutation in ATP synthase allows the passage of H+ ions but does not produce ATP. When grown in aerobic conditions, would you expect Cell Y to generate a little less OR a little more...
