A)External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.
B)Aerobic respiration needs oxygen to occur, while anaerobic does not. This presence of oxygen determines what products will be created. During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are created
C)Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. ... For example, both processes synthesize and use ATP, the energy currency.
ATP is required for muscle contraction. ...
A small amount of free ATP is available in the muscle for immediate use.
Phosphocreatine provides phosphates to ADP molecules, producing high-energy ATP molecules. ...
Glycolysis converts glucose to pyruvate, water and NADH, producing two molecules of ATP
