Cards

Term
adenylate kinase -
Definition
important enzyme in cellular energy balance; a nucleoside monophosphate kinase that transfers a phosphate from one ADP to another ADP to form ATP and AMP
Term
aerobic glycolysis -
Definition
the pathway in which glucose is oxidized and cleaved to form pyruvate in the presence of oxygen
Term
ADP -
Definition
adenosine diphosphate; a nucleotide consisting of adenine, the sugar D-ribose, and two phosphate groups that is formed by the removal of one phosphate from an ATP molecule by enzymes called ATPases
Term
allosteric activation -
Definition
increase in enzyme activity by binding of an effector at an allosteric site that affects binding or turnover at the catalytic site
Term
AMP -
Definition
adenosine monophosphate; a nucleotide consisting of adenine, the sugar D-ribose, and one phosphate group that can be formed during ATP synthesis from 2 ADP molecules or the hydrolysis of one phosphate bond from an ADP molecule; can also exist as a cyclic structure known as cyclic AMP (or cAMP)
Term
anaerobic glycolysis -
Definition
the pathway in which glucose is oxidized and cleaved to form pyruvate in the absence of oxygen; pyruvate is then reduced to lactate.
Term
aspartate -
Definition
a nonessential amino acid that can be produced from oxaloacetate by transamination; functions as a metabolite in the urea cycle and participates in gluconeogenesis; carries reducing equivalents in the malate-aspartate shuttle
Term
B-cells -
Definition
type of cell in the pancreas that makes and releases insulin and play a critical role in diabetes mellitus types 1 and 2; located in areas of the pancreas called the islets of Langerhans
Term
1,3-bisphosphoglycerate -
Definition
3-carbon organic molecule that is an intermediate of glycolysis
Term
blood glucose -
Definition
the amount of glucose present in the blood; normally increases after a meal and gradually returns to basal levels; chronically high blood glucose levels can damage the eyes, kidneys, nerves, and blood vessels
Term
blood lactate -
Definition
lactic acid that is present in the blood as a result of anaerobic metabolism when oxygen delivery to the tissues is insufficient to support normal metabolic demands
Term
Cori cycle -
Definition
the metabolic pathway in which lactate produced by anaerobic glycolysis is 'recycled'- it is moved to the liver where it is converted to glucose, then the glucose returns to the muscles and is converted back to lactate [1]
