Well, they don't exactly 'eat' it. Glucose (sugar used in cells) diffuses into the cells from blood plasma, aided by insulin. Once inside the cell, glucose moves to the mitochondria of the cell where cellular respiration (Krebs cycle) breaks the glucose down by the use of an electron transport chain, and the chemical energy released when the C-H bonds are broken in the glucose to form CO2 and H2O is stored in ATP molecules by a process called active phosporylation. It is a complex cycle, but the summary is:
Glucose (C6H12O6) molecules are broken apart to form wastes, CO2 and H2O. The C-H bonds in the glucose are rich in chemical energy, and the purpose of breaking the glucose down is to release that chemical energy and use it to add phosphate ions to AMP (adenosine monophosphate), making first ADP(adenosine diphosphate) and then ATP (adenosine triphosphate). ATP molecules hold the chemical energy in the bonds of the 2 phosphate ions that have been added to them in this process, and the cell can 'spend' that energy for metabolic reactions in the cell by breaking off the two phosphates, releasing that chemical energy into the reactions.
The B vitamin that helps to make new cells is called folate. It is also needed for the construction of DNA and is the most needed prenatal vitamin.
The mitochondrial spiral in sperm cells helps provide the energy needed for the sperm to swim and reach the egg during fertilization. This spiral arrangement of mitochondria produces ATP, which fuels the movement of the sperm's tail for motility.
Cells use blood sugar, or glucose, as a primary source of energy through a process called cellular respiration. Glucose is broken down in the cell to produce ATP, the energy currency of cells. Insulin helps cells take up glucose from the bloodstream to fuel various cellular functions.
Increased blood flow delivers more oxygen and nutrients to muscle cells, enhancing their ability to produce energy through aerobic metabolism. This process results in higher ATP production and improved muscle function during physical activity. Additionally, better blood flow helps remove waste products, such as lactic acid, which can impede energy production in muscle cells.
Respiration is important because it is the process through which cells obtain energy from glucose molecules. This energy is essential for all cellular activities, such as growth, repair, and maintenance of the body. Without respiration, cells would not be able to function and the body would not be able to survive.

Water is needed by all plants to carry nutrients from the soil to the cells and transport waste products away from the cells through a process called transpiration. Water also helps plants maintain their structure and turgidity.
Red blood cells obtain energy through a process called glycolysis, where they break down glucose to produce ATP, the energy currency of cells. This ATP helps the red blood cells carry out their important function of transporting oxygen throughout the body.
The TCA cycle is regulated through feedback inhibition and enzyme activity to ensure efficient energy production in cells. Key enzymes in the cycle are controlled by levels of ATP, NADH, and other molecules to maintain a balance of energy production. This regulation helps cells produce the right amount of energy needed for their functions.
The cell is the functional basic unit of life, and it is the smallest unit of life classified as a living thing. Really hope this helps! :)
From the chemical energy stored inn the cells of food =) hope this helps
Mitochondria.
The small parts of cells are called organelles. These specialized structures within cells perform specific functions that are essential for the cell's survival and activity. Examples of organelles include the nucleus, mitochondria, and chloroplasts.
The mitochondrial spiral in sperm cells helps provide the energy needed for the sperm to swim and reach the egg during fertilization. This spiral arrangement of mitochondria produces ATP, which fuels the movement of the sperm's tail for motility.
