Question

1. what happens to glucose during glycolysis? a. it is converted into water and carbon dioxide. b. it is broken down into pyruvate and atp. c. it is stored in the mitochondrion for later use. d. it combines with oxygen to produce energy. 9. what happens to pyruvate after glycolysis if oxygen is present? a. it is broken down into carbon dioxide in the cytoplasm. b. it is converted back into glucose. c. it is transported into the mitochondrion to enter the citric acid cycle. d. it is directly used to generate atp in the nucleus. 10. what is the primary purpose of cellular respiration? a. to produce glucose from pyruvate. b. to synthesise proteins. c. to break down dna. d. to convert energy from nutrients into atp. 11. what is the significance of independent assortment in meiosis? a. it increases genetic variation by randomly distributing chromosomes to gametes. b. it preserves genetic diversity in offspring. c. it produces diploid cells from haploid cells. d. it ensures that all chromosomes are identical. 12. what is the result of meiosis? a. four haploid cells with identical genetic material. b. two diploid cells with double the number of chromosomes. c. two haploid cells with half the number of chromosomes as the original diploid cell. d. two diploid cells identical to the parent cell. 13. what is the primary purpose of the light - independent reactions? a. to convert carbon dioxide into glucose. b. to release oxygen into the atmosphere. c. to capture light energy. d. to break down glucose into atp. 14. what is the final outcome of meiosis? a. two identical diploid cells. b. two non - identical haploid cells. c. four non - identical haploid gametes. d. four identical diploid cells.

Explanation:

• For the first question about what happens to glucose during glycolysis, glucose is broken down into pyruvate and ATP is produced.
• For the second question about pyruvate after glycolysis in the presence of oxygen, it is transported into the mitochondria to enter the Citric - Acid Cycle.
• For the third question about the primary purpose of cellular respiration, it is to convert energy from nutrients into ATP.
• For the fourth question about the application of independent assortment in meiosis, it increases genetic variation by randomly distributing chromosomes to gametes.
• For the fifth question about the result of meiosis, it produces four haploid cells with different genetic material.
• For the sixth question about the primary purpose of the light - independent reactions, it is to convert carbon dioxide into glucose.
• For the seventh question about the final outcome of meiosis, it is four non - identical haploid gametes.
