verb (used without object), re·spired, re·spir·ing. to inhale and exhale air for the purpose of maintaining life; breathe.

In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction. In contrast, exhalation (breathing out) is usually a passive process.

noun Physiology. the oxidation of organic compounds that occurs within cells, producing energy for cellular processes.

Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water. …

Oxygen is used in cellular respiration. For example, the monosaccharide glucose, (the most basic form of carbohydrate) can be combined with oxygen. The high energy electrons that are found in the glucose are transferred to the oxygen and potential energy is released. The energy is stored in the form of ATP.

Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals. Cellular respiration begins in the cytoplasm of cells. It is completed in mitochondria.

It is very hard to quantify and say exactly how long it takes for one round of cellular respiration. We do know that it occurs very quickly. Cells do not stockpile ATP which means that as soon as ATP is used up more needs to be made. Cellular respiration, more than likely, occurs in milliseconds.

Respiration (breathing) is the way your body gets oxygen into the lungs from the air outside. Cellular respiration describes how your cells make ATP – a molecule used to provide energy for chemical reactions.

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain.

Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O.

The Calvin cycle is part of the light-independent reactions of photosynthesis. The Calvin cycle uses ATP and NADPH. The Krebs cycle is part of cellular respiration. This cycle makes ATP and NAPH.

What two ways foes cellular respiration occur in? It occurs in two main stages: krebs cycle (stage 1) and electron transport (stage 2).

Stage 2: Small molecules are broken down further using oxygen and releasing much more energy. How is breathing related to cellular respiration? Breathing brings in oxygen that is used in cellular respiration and removes waste products such as carbon dioxide.

The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Mitochondria, organelles specialized to carry out aerobic respiration, contain an inner membrane folded into cristae, which form two separate compartments: the inner membrane space and the matrix. The Krebs Cycle takes place in the matrix.

Glycolysis, as we have just described it, is an anaerobic process. None of its nine steps involve the use of oxygen. However, immediately upon finishing glycolysis, the cell must continue respiration in either an aerobic or anaerobic direction; this choice is made based on the circumstances of the particular cell.

Answer: the process of breathing(respiration) divided into two district phases, inspiration (inhalation) and expiration ( inhalation).

mitochondria

Cellular respiration breaks glucose down into water, carbon dioxide, and energy. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.

During cellular respiration, the reactants—glucose (sugar) and oxygen—combine together to form new products: carbon dioxide molecules and water molecules. Adenosine triphosphate (ATP) is produced as the form of energy that can be used for other cellular processes.

Totipotent cells are cells that can mature into any type of body cell in an organism including the cells that make up the placenta in mammals.

The known and well characterized totipotent stem cells are found only in early embryonic tissues and derive usually from the first few cell divisions after fertilization.

A cell that can differentiate into all cell types of the adult organism is known as pluripotent. Such cells are called meristematic cells in higher plants and embryonic stem cells in animals, though some groups report the presence of adult pluripotent cells.

Embryonic stem cells are the cells within the protective layer of the blastocyst. They are pluripotent, which means they can develop into any of the cells of the adult body.

A totipotent cell has the potential to divide until it creates an entire, complete organism. Pluripotent stem cells can divide into most, or all, cell types in an organism, but cannot develop into an entire organism on their own.
