Answer:
Oxygen
Explanation:
Oxygen (65%) and hydrogen (10%) are predominantly found in water, which makes up about 60 percent of the body by weight.
Answer: (c) Gluconeogenesis
Explanation:
Gluconeogenesis (“new formation of glucose”) uses amino acids and lactic acid obtained from muscle proteins to convert into glucose. The glucocorticoids stimulate the liver to produce the enzymes needed for gluconeogenesis, the conversion of amino acids into glucose. This creation of glucose from protein is particularly important during very long periods of fasting or exercise when blood glucose levels might otherwise become dangerously low.
Answer: B and C
Explanation:
Option A is wrong because only one glucose molecule is needed to initiate glycolysis
Option B is correct the major product of Glycolysis is 2 molecules Pyruvate, 4 ATP and 2 NADH are also produced at the end of glycolysis.
Option C is correct Glycolysis is the process by which glucose is converted to two molecules of PYRUVATE.
Option D is wrong because Glycolysis occurs in the cytoplasm of the cell.
Option E is also wrong because Glycolysis is an ANAEROBIC process
Answer is B and C
