The process is known as secretion

Explanation:

When we talk about how Contents in the peritubular capillaries are actively transported into proximal and distal convoluted tubules in a process known as secretion, then we need to mention the kidney as the chief organ that made this possible. Secretion which has waste substance such as hydgoen ions, excess water removed from the blood is part of the process involved in the excretion of urine. Peritubular capillaries are important in the reabsorption and secretion process of urine formation and removal to the bladder. From the question, when they drain their contents into proximal and distal convoluted tubules then the process is called secretion.

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.
