Cells a and b are the same size, shape, and temperature, but cell a is metabolically less active than cell b. and cell b is actively converting oxygen to water in cellular respiration. oxygen will diffuse more rapidly into cell because

The answer is b; the diffusion gradient in cell B is steeper. Both cells would lose water; the red blood cell would shrivel, and the plant plasma membrane would pull away from the cell wall. Transport proteins in the membrane or Facilitated diffusion of solutes may occur through channel.

the answer is b: 1.4 km/hr

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
