Document Summary
Respiration is the chemical reactions that break down nutrient molecules in living cells to release energy. In humans, our cells need energy (atp) for: Making protein molecules: linking together amino acids into long chains. Cell division: to repair damaged tissues and so that we can grow. Maintenance of constant body t transmitting nerve impulses. All this energy comes from the food we eat. Water soluble molecules are absorbed from the intestine into the blood. The main energy providing nutrient: glucose (contains a lot of chemical energy). Video atp & respiration: crash course biology #7 https://www. youtube. com/watch?v=00jbg_cfguq. There are 2 kinds of respiration: aerobic and anearobic. The main difference between them is that aerobic respiration involves oxygen and anaerobic respiration does not: aerobic respiration. The release of a relatively large amount of energy in cells by the breakdown of food substances in the presence of o2: anaerobic respiration.
