Answer:
Reabsorption takes place mainly in the proximal convoluted tubule of the nephron .
The best answer is ATP (Adenosine triphosphate).
Metabolism is a term referring to the overall processes by which energy is obtained by an organism. In man it begins with the digestion process, and ends with cellular respiration.
Food molecules are broken down into their monomer units through the digestive process. Carbohydrates are broken into glucose units. Glucose is taken in by cells and used in cellular respiration to produce ATP, which is the form of energy that cells use.
Cellular respiration involves three stages namely glycolysis , Krebs cycle and electron transport chain. From one molecule of glucose, the number of ATP molecules generated through cellular respiration is 36 to 38 molecules.

<h2>
Nucleus - control center</h2>
The nucleus is called the control center of the cell because:
- The genetic material which is the essence of life is hosted in the nucleus – the DNA-which presents the code of life or information or instructions regarding:
- The structure and function of each cell and the organ it is present,
- Numerous activities of life like reproduction, metabolism, growth, development, etc.
- The nucleus replicates the genetic information and passes to the new daughter cells, generation after generation to continue the life processes.
- The nucleus DNA transcribes the code or information for protein synthesis to the RNA to synthesize proteins in the body which carry out many essential functions in the form of structural proteins, antibodies, hormones, pigments, etc.
- The nucleus DNA synthesizes enzymes which carry out functions like metabolism.
