How do cells turn food into energy?

Question

How do cells turn food into energy?

Answer 1

it`s called metabolism. food gets broken down, then simple copmound proceed to mitochondrias, where they get turned into ATP, or highly energized compound, universal fuel for any cell processes.

Answer 2

"Cellular respiration."  Energy from glucose is used to make energy in ATP.  Energy from ATP is coupled with the other metabolic reactions of the cell, to provide energy.

Answer 3

All types of food are converted into some  carbohydrate of six carbon compound or less and are fed into the classical cycle(TCA) to yield energy.

Answer 4

Metabolism is the means by which cells turn food into energy. This site here explains all of that in depth. Hope it helps.

Answer 5

Cell turns food into energy by a process called respiration. Our cell add oxygen to the food which results in the release of enrgy .The respiration process is shown below

Food+ Oxygen --> Energy + Carbondioxide + Water.

Answer 6

Cells turn food into energy by a process called cellular respiration. It begins with the stage of glycolisis (which takes place in the cytoplasm of the cell), where two ATP (chemical energy in its simplest form) molecules are used to split a glucose molecule into two pyruvate acid molecules and produces some ATP. Hydrogen-carrier proteins called NAD+ and FAD+ pick up hydrogen molcules (NAD+ --> NADH and FAD+ --> FADH2) as a result of the glucose being split.

The pyruvates are then brought into the mitrochondria of the cell and go through the aerobic process of the Kreb's Cycle where a pyruvate is bonded to oxyllo acetate and becomes citric acid. It is referred to as aerobic because it requires the intake of oxygen to carry out, and expels carbon dioxide as a by-product. FAD+ and NAD+ pick up hydrogen molecules that come from the citric acid being broken down. These hydrogen-carrier proteins transport hydrogen molecules to an Electron Transport Chain, still within the mitrochondrion. The concentration of hydrogen molecules in the inner membrane of the mitrochondrian creates a concentration gradient and the hydrogen molecules begin to diffuse through the inner membrane, creating energy which is harvested to bond ADP and a phosphate together to create ATP. The hydrogen molecules bond to oxygen molecules (the Electron Transport Chain is also an aerobic process) to create water and a net gain of 34 ATP molecules is made.

In the case of some organisms, where oxygen is not available, the cell will resort to lactic acid or alcoholic fermentation in place of the Kreb's Cycle and Electron Transport chain in order to make use of the hydrogen molecules from NADH and FADH2 so that glycolisis can continue.
