How are cellular respiration defined?
Cellular respiration can be defined simply as a series of metabolic processes that take place within a cell. Biochemical energy is harvested from organic substances (e.g. glucose) and then stored in energy-carrying biomolecules (e.g. adenosine triphosphate or ATP) for use in the energy-requiring activities of the cell.
What are 4 characteristics of cellular respiration?
The overall mechanism of cellular respiration involves four subdivisions: glycolysis, in which glucose molecules are broken down to form pyruvic acid molecules; the Krebs cycle, in which pyruvic acid is further broken down and the energy in its molecule is used to form high-energy compounds such as NADH; the electron …
How will you describe cellular respiration in your own words?
Cellular respiration is the process of breaking sugar into a form thatthe cell can use as energy. This happens in all forms of life. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobicrespiration.
What are the synonyms for cellular respiration?
Synonyms for Cellular respiration:
- n. •act (noun) internal respiration, respiration, cellular respiration. •Other relevant words: (noun) metabolism, metastasis, metabolic process.
- Other synonyms: • Other relevant words: metamorphosis, ventilating system, airing, public discussion, eupnoeic, cell biology,
What are the 2 types of cellular respiration?
There are two main types of cellular respiration—aerobic respiration and anaerobic respiration. Aerobic respiration is a specific type of cellular respiration, in which oxygen (O2) is required to create ATP.
Where does cellular respiration process takes place?
Key Terms
| Term | Meaning |
|---|---|
| Mitochondria | The eukaryotic cell structure where cellular respiration occurs |
| Cytoplasm | The contents of a cell between the plasma membrane and the nuclear envelope; includes cytosol which is the jelly-like substance that fills the space between organelles |
| Aerobic | Process that requires oxygen |
How does cellular respiration work simple?
Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists. Glucose, a simple sugar, provides the fuel the cell needs.
Which is the correct definition of cellular respiration?
Cellular Respiration Definition Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
cellular respiration in Science. The process of cell catabolism in which cells turn food into usable energy in the form of ATP. In this process glucose is broken down in the presence of molecular oxygen into six molecules of carbon dioxide, and much of the energy released is preserved by turning ADP and free phosphate into ATP.
How is potential energy released in cellular respiration?
The potential energy of the protons generated by one acetyl group is later released when they recross the membrane and are used to form three molecules of ATP from ADP and phosphate in the process of oxidative phosphorylation. The pyruvate from one molecule of glucose drives two turns of the Krebs cycle.
Why do plants and animals need cellular respiration?
Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function.
