Answer:
2
Explanation:
Glycolysis or EMP pathway is first stage of cellular respiration that occur in the cytoplasm of every living cell. It is a common process of both anaerobic and aerobic respiration. During glycolysis glucose, a 6 carbon sugar is converted into two molecules of pyruvate, a three carbon sugar. During this conversion 4 ATP molecules are produced. Two oxidise glucose to pyruvate, 2 ATP molecules are also required or used up. Thus, a net gain of 2 ATP molecules at the completion of glycolysis.
Answer:
As paramecium lives in fresh water, it has the problem of water being transported into it because of osmosis.
Explanation:
osmosis is the movement of any solvent through a selectively permeable membrane into an area of higher solute concentration, the result of which will be an equalizing of solute concentration on either side of the membrane.
