Answer:
Enzymes are biological catalysts that increase the rate of chemical reactions inside cells by lowering the activation energy required for the reaction to proceed. In nature, exergonic reactions do not require energy beyond activation energy to proceed, and they release energy.
Answer:
1. kidneys 2. Lungs 5. Pancreas
Explanation:
The body's balance between acidity and alkalinity in the human body is regarded as the acid-base balance which is measured on the basis of the pH and the concentration of carbon dioxide and bicarbonate in the blood. The organs that controls acid-base balance are lungs, kidneys and pancreas. Theses organs control blood pH by releasing carbon dioxide from the lungs because it is a waste product slightly acidic in nature and excreting excess of acids and bases from the body.
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
