Creatine KINASE
creatine kinase
a hexokinase is an enzyme that catalyzes the phosphorylation of hexoses.
Actually, there are 3 pathways for creating ATP for muscle contraction. 1) Direct phosphorylation of ADP by creatine phosphate, 2) aerobic respiration and 3) anaerobic glycolysis & lactic acid formation.
One way to control an enzyme is through post-translational modification such as phosphorylation or glycosylation. Other ways to control enzymes are through enzyme induction, inhibition, or by compartmentalizing the metabolic pathways.
DNA Helicase. - an enzyme, is responsible for unwinding and unzipping the double helix.
creatine kinase
The reaction of creatine phosphate with ADP is catalyzed by the enzyme creatine kinase and is reversible.
Creatine phosphate + ADP_______> creatine + ATP This is catalyzed by the enzyme creatine kinase.
glucokinase
a hexokinase is an enzyme that catalyzes the phosphorylation of hexoses.
An acetokinase is an enzyme which catalyzes the phosphorylation of acetate as part of the process of glycolysis.
Sources of ATP include the phosphorylation of ADP by creatine phosphate, anaerobic glycolysis, and oxidative phosphorylation of ADP n the mitochondria.
Actually, there are 3 pathways for creating ATP for muscle contraction. 1) Direct phosphorylation of ADP by creatine phosphate, 2) aerobic respiration and 3) anaerobic glycolysis & lactic acid formation.
Phosphoglycerate kinase in glycolysis
Creatine phosphate, oxidative phosphorylation, and glycolysis.
In general they will get most of their energy from creatine phosphate and not go through oxidative phosphorylation.
Inorganic phosphate can be used as an inhibitor under covalent modification. Phosphorylation/ Dephosphorylation can either activate or deactive an enzyme.
