Question

1. which stage of cellular respiration produces the most atp?

a. glycolysis
b. citric acid cycle
c. electron transport chain
d. fermentation

1. which of the following best describes the process of osmosis?

a. movement of ions through active transport
b. movement of water molecules through a selectively permeable membrane from high to low concentration
c. movement of proteins through the cell membrane
d. movement of small nonpolar molecules through the cell membrane

1. what is the main purpose of meiosis ii?

a. to double the chromosome number
b. to maintain genetic uniformity
c. to separate sister chromatids into different cells
d. to pair up homologous chromosomes

Explanation:

1. In cellular respiration, the electron - transport chain generates the most ATP through oxidative phosphorylation. Glycolysis and the citric - acid cycle produce fewer ATPs compared to it, and fermentation produces a small amount of ATP.
2. Osmosis is defined as the movement of water molecules through a selectively permeable membrane from an area of high water concentration to an area of low water concentration.
3. The main purpose of Meiosis II is to separate sister chromatids into different cells, resulting in the formation of four haploid cells from the two haploid cells produced in Meiosis I.

Answer:

1. C. Electron Transport Chain
2. B. Movement of water molecules through a selectively permeable membrane from high to low concentration
3. C. To separate sister chromatids into different cells
