Hibernating animals have tissues containing mitochondria with a membrane protein that accelerates electron transport while blocking the synthesis of ATP. What is the consequence of this?
1 Energy is saved because glycolysis and the citric acid cycle shuts down.
2 The energy of respiration is converted into heat.
3 Hibernating animals can synthesize fat instead of wasting energy of respiration.
4 Pyruvate is converted to lactic acid by anaerobic fermentation.
Explanation:
In mammals there are two types of adipose tissues: white and brown. Brown fat cells contain a great many mitochondria, and brown adipose tissue is well supplied by blood capillaries. Brown adipose tissue produces considerable amount of heat, because their lipids are respired with little or no ATP formation; most energy is released as heat. This heat is transported in the blood to the body organs.

When one molecule of glucose is completely oxidised during aerobic respiration, how many molecules of carbon dioxide are released due to tricarboxylic acid cycle?
1 One
2 Two
3 Three
4 Six
Explanation:
Six carbon dioxide molecules are released by complete oxidation of one glucose molecule. Two carbon dioxide molecules are released during oxidative decarboxylation reaction and four carbon dioxide molecule are released in Kreb's cycle or tricarboxylic acid cycle.
