DefinitionTerm
this conveys the carbon atoms within the acetyl group (C2 from pyruvate) to the citric acid cycle to be oxidized for energy production.
a gas (that is a combination of carbon and oxygen) that is involved in just about every reaction in and around cellular respiration.
During the cycle, acetyl-CoA (2 carbons) + oxaloacetate (4 carbons) yields citrate (6 carbons), which is rearranged to a more reactive form called isocitrate (6 carbons)
the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. The first step in is
Lactate loses electrons to become Pyruvate.
Takes place in the cristae of the mitochondria, and consists of 3 protein complexes and 2 carriers.
the movement of ions across a selectively permeable membrane, down their electrochemical gradient. More specifically, it relates to the generation of ATP by the movement of hydroge
the metabolic pathway in which the mitochondria in cells use their structure, enzymes, and energy released by the oxidation of nutrients to reform ATP.
an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP)
An acid produced in anaerobic respiration during lactic acid fermentation.
Takes place in the cytoplasm outside the mitochondria, a long series of reactions used to generate 2 pyruvate, 2 NADH, and 4 ATP, does not require oxygen. Consists of 2 main steps:
this respiration is the process of producing cellular energy without oxygen. It is a relatively fast reaction and produces 2 ATP, which is far fewer than aerobic respiration.
The product of the electron transport chain. A higher concentration of protons outside the inner membrane of the mitochondria than inside the membrane is the driving force behind A
non-protein organic molecules that bind with the protein molecule to form the active enzyme
the process by which cells acquire energy by breaking down nutrient molecules produced by photosynthesizers, and involves the processes of glycolysis, the preparatory reaction, and
DefinitionTerm
also known as the citric acid cycle, a cyclical metabolic pathway located in the matrix of the mitochondria
A mitochondrion (singular) has a double membrane with an intermembrane space. Cristae are folds of inner membrane that jut out into the matrix, the innermost compartment, which is
a kinase enzyme that phosphorylates fructose 6-phosphate in glycolysis
an organic molecule (not a protein) dissolved in the hydrophobic region of the inner membrane of the mitochondrion that acts as an electron transfer agent.
the set of metabolic pathways that construct molecules from smaller units
this occurs when the final product of an active site binds back to the first enzyme’s allosteric site and stops production of the product.
Innermost compartment of the mitochondria, with an inside space of gel-like fluid
a type of chemical reaction that involves a transfer of electrons between two species
powerful bonds which serve as the main power sources of the cell’s reactions
2 molecules of this are made per glycolysis cycle. They are then used in the preparatory cycle. C3 pyruvate is converted into a C2 acetyl group and CO2 is giving off.
the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy, or used in other anabolic reactions.
a type of metabolic reaction that results in the formation of adenosine triphosphate (ATP) by the direct transfer and donation of a phosphoryl (PO3) group to adenosine diphosphate
Membrane that runs along the cristae where the ETC takes place
Location of the ETC, folds of inner membrane that jut out into the matrix.
Produces limited amounts of ATP in the absence of oxygen (it is an anaerobic reaction)
