Water, electrolytes, and nutrients like glucose and amino acids are reabsorbed in the kidneys from the primary filtrate to help maintain proper balance in the body.
Essential materials like water, glucose, amino acids, and electrolytes (such as sodium, potassium, and calcium) are reabsorbed back into the blood from the nephric filtrate to maintain the body's balance. Substances like waste products and excess ions are eliminated through urine.
The useful product of glycolysis for the cell is ATP, which is the energy currency of the cell. Glycolysis produces a net of 2 ATP molecules per glucose molecule, along with 2 molecules of pyruvate that can be further used in cellular respiration to generate more ATP.
Reabsorption in the proximal tubule involves the passive and active transport of glucose, amino acids, ions, and water from the tubular fluid back into the bloodstream. This reabsorption process helps maintain the body's electrolyte balance and conserve valuable nutrients. It is highly efficient due to the presence of a brush border with microvilli that increases surface area for absorption.
The digestive system and the circulatory system are the two body systems most useful in getting nutrients. The digestive system breaks down food into smaller molecules, allowing nutrients to be absorbed in the intestines. Once absorbed, the circulatory system transports these nutrients throughout the body to cells and tissues where they are needed for energy, growth, and repair. Together, these systems ensure that the body receives the essential nutrients required for overall health.

it is good for you. it has valuable nutrients.
Starch and glycogen are useful as energy storage molecules because they are composed of glucose monomers linked in a way that allows for easy hydrolysis, releasing glucose for energy when needed. In contrast, cellulose has a rigid structure due to its β-glucose linkages, making it ideal for providing structural support in plant cell walls. Humans cannot break down cellulose because we lack the enzyme cellulase, which is necessary to hydrolyze the β-glycosidic bonds between the glucose units in cellulose. As a result, cellulose passes through the digestive system undigested, contributing to dietary fiber instead.
Glucose is considered the most useful biological fuel because it is a primary source of energy for cells in the body. It is readily available from the breakdown of carbohydrates in our diet, and it can be efficiently converted into ATP through cellular respiration to power various cellular processes. Additionally, glucose is a versatile molecule that can be easily metabolized by a wide range of organisms for energy production.
