What is cellular respiration Bioninja?
What is cellular respiration Bioninja?
Cell respiration is the controlled release of energy from organic compounds to produce ATP. ATP from cell respiration is immediately available as a source of energy in the cell. Aerobic cell respiration requires oxygen and gives a large yield of ATP from glucose.
What is glycolysis Bioninja?
Glycolysis involves the breakdown of glucose into pyruvate (× 2), with a small net gain of ATP (two molecules) Glycolysis occurs in the cytosol and does not require oxygen (it is an anaerobic process)
What is anaerobic cell respiration?
Anaerobic respiration is a type of respiration where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors. Fermentation includes processes that use an organic molecule to regenerate NAD+ from NADH.
What is ATP used for Bioninja?
ATP has two key functions within the cell: It functions as the energy currency of the cell by releasing energy when hydrolysed to ADP (powers cell metabolism) It may transfer the released phosphate group to other organic molecules, rendering them less stable and more reactive.
What is Chemiosmosis IB bio?
The accumulation of H+ ions in the intermembrane space creates an electrochemical gradient (or a proton motive force) H+ ions return to the matrix via the transmembrane enzyme ATP synthase (this diffusion of ions is called chemiosmosis)
How do Respirometers work?
A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. As an organism takes up O2, it generates a proportionate quantity of CO2 (see respiratory quotient), but all the CO2 is absorbed by the soda lime. …

What is photosynthesis IB Biology?
Photosynthesis is the process by which cells synthesise organic molecules (e.g. glucose) from inorganic molecules (CO2 and H2O) in the presence of sunlight. This process requires a photosynthetic pigment (chlorophyll) and can only occur in certain organisms (plants, some bacteria)
What is chemiosmosis Bioninja?
What is ATP IB?
Adenosine triphosphate, or ATP, is the primary carrier of energy in cells. adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
What are the stages of anaerobic respiration?
The four stages of aerobic respiration are glycolysis, acetyl-CoA, Krebs cycle and the electron transport chain. Aerobic respiration is the process by which the body produces ATP , an important substance that is needed for the survival of cells. During the first phase, glycolysis , glucose is broken down in the cytoplasm of the cells.
What describes anaerobic cell respiration?
Anaerobic respiration. Definition. noun. (1) A form of cellular respiration that occurs when oxygen is absent or scarce. (2) The process of generating energy by the oxidation of nutrients and using an external electron acceptor other than oxygen.
Is cellular respiration anaerobic?
Anaerobic respiration. Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor (such as oxygen) to produce large amounts of energy, to drive the bulk production of ATP . Anaerobic respiration is used by some microorganisms in which neither oxygen (aerobic respiration)…
What is cellular respiration?
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.
