What breaks down molecules to make ATP?

What breaks down molecules to make ATP?

Chemical process where mitochondria break down food molecules to produce ATP, the three stages are glycolysis, the citric acid cycle, and the electron transport chain. Molecule formed from the breaking off of a phosphate group from ATP; results in a large release of energy that is used for biological reactions.

What breakdown of food produces ATP?

Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP. When excess ATP and glucose are present, the liver converts them into a molecule called glycogen, which is stored for later use.

What do cells use to break down food molecules?

Autotrophs and heterotrophs do cellular respiration to break down food to transfer the energy from food to ATP. The first two, glycolysis and the Krebs cycle, break down food molecules. The third pathway, oxidative phosphorylation, transfers the energy from the food molecules to ATP.

How do cells generate ATP in the absence of oxygen?

Fermentation. Some organisms are able to continually convert energy without the presence of oxygen. They undergo glycolysis, followed by the anaerobic process of fermentation to make ATP.

Is the process that breaks down organic molecules for the production of ATP?

Through the process of cellular respiration, cells make the carbon in glucose into stable carbon dioxide molecules and produce energy. Energy is also released and used to make ATP (adenosine triphospate), an organic molecule that is the main energy source for cell processes.

How is glycogen used to make ATP?

During intense, intermittent exercise and throughout prolonged physical activity, muscle glycogen particles are broken down, freeing glucose molecules that muscle cells then oxidize through anaerobic and aerobic processes to produce the adenosine triphosphate (ATP) molecules required for muscle contraction.

Can glycolysis produce ATP in the absence of oxygen?

Glycolysis produces only two net molecules of ATP per 1 molecule of glucose. However, in cells lacking mitochondria and/or adequate oxygen supply, glycolysis is the sole process by which such cells can produce ATP from glucose.

What is the pathway of ATP formation through cellular respiration?

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Which is part of the cell breaks down food molecules?

cells organelles surrounded by two membranes that break down food molecules to make ATP, can only work if they have oxygen chloroplast an organelle found in plant and algae cells where photosynthesis occurs”solar power plant” make food using the energy of sunlight photosynthesis

How are cells able to obtain energy from food?

The proteins, lipids, and polysaccharides that make up most of the food we eat must be broken down into smaller molecules before our cells can use them- either as a source of energy or as building blocks for other molecules.

Which process requires ATP molecules as a source of energy?

Cellular respiration is the process by which organic compounds (preferably glucose) are broken apart, releasing energy that is used to produce ATP molecules. Cells need to have ATP because it’s the gasoline that powers all living things. ATP is a high energy nucleotide which acts as an instant source of energy within the cell.

What kind of organelles are needed to make ATP?

Which is an organelle found in plant and algae cells?
