Question

1. mitochondria require glucose to convert adp to atp. which of the following statements describes how adp is converted into atp? (a) adp loses a phosphate group which stores energy for use by the cell. (b) adp gains a phosphate group which stores energy for use by the cell. (c) adp loses a phosphate group which releases energy for use by the cell. (d) adp gains a phosphate group which releases energy for use by the cell. 5. all living organisms break down sugars to obtain energy in a process called cellular respiration. cellular respiration may take place in the presence of oxygen (aerobic) or without oxygen (anaerobic). which of these equations shows anaerobic cellular respiration? (a) glucose + lactose → oxygen + water (b) glucose → lactic acid + water + carbon dioxide (c) glucose + ethyl alcohol → carbon dioxide + energy (d) carbon dioxide → glucose + oxygen + water + energy 6. which organelle is the site of cellular respiration?

Explanation:

Question 4:

ATP is formed when ADP gains a phosphate group through a process called phosphorylation. This stores energy in the high - energy phosphate bond for the cell to use later.

Question 5:

In anaerobic cellular respiration in animals, glucose is converted into lactic acid, water and carbon dioxide. In plants, glucose can be converted into ethyl alcohol and carbon dioxide during anaerobic respiration. But the most common anaerobic pathway in animals is the one that produces lactic acid from glucose.

Question 6:

Mitochondria are the power - houses of the cell and the site of cellular respiration. The structure shown in option A is a mitochondrion with its characteristic double - membrane and cristae.

Answer:

Question 4: B. ADP gains a phosphate group which stores energy for use by the cell

Question 5: B. glucose → lactic acid + water + carbon dioxide

Question 6: A. (the mitochondrion structure)
