In humans, oxygen and carbon dioxide are exchanged between the alveoli in the lungs and the blood in the circulatory system. Which of the following processes allows for the exchange of these gases in the human body? osmosis

simple diffusion

active transport

facilitated diffusion

Simple diffusion

Explanation:

Diffusion is a process in which material travels from regions of high concentration to low concentration until equilibrium is reached. Gas molecules move from a region in which they are at high concentration to one in which they are at low concentration. Diffusion is a passive process, meaning that no energy is required to power the transport, and it follows Fick's Law

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.
