MUSCLE PHYSIOLOGY

Detailed explanation-1: -Kinases constitute a key class of enzymes responsible for the regulation of many biological phenomena. By covalently attaching a phosphate group to its target (phosphorylation) a kinase is able to regulate a particular biological reaction.

Detailed explanation-2: -Whereas phosphatases remove phosphate groups from molecules, kinases catalyze the transfer of phosphate groups to molecules from ATP.

Detailed explanation-3: -(KY-nays) A type of enzyme (a protein that speeds up chemical reactions in the body) that adds chemicals called phosphates to other molecules, such as sugars or proteins. This may cause other molecules in the cell to become either active or inactive. Kinases are a part of many cell processes.

Detailed explanation-4: -(pyruvate kinase)-phosphatase CAS no. This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is [ATP:pyruvate 2-O-phosphotransferase]-phosphate phosphohydrolase.
