Which enzyme has decreased activity when phosphorylated?
enzyme glycogen synthetase
Enzyme Activity For example, phosphorylation of the enzyme glycogen synthetase changes the enzyme’s shape and reduces its activity. The enzyme catalyzes the conversion of the small sugar, glucose, to the long-chain starch glycogen.
What enzymes break down molecules?
amylase and other carbohydrase enzymes break down starch into sugar. protease enzymes break down proteins into amino acids. lipase enzymes break down lipids (fats and oils) into fatty acids and glycerol.
How are polypeptides broken down?
In human digestion, proteins in food are broken down into smaller peptide chains by digestive enzymes such as pepsin, trypsin, chymotrypsin, and elastase, and into amino acids by various enzymes such as carboxypeptidase, aminopeptidase, and dipeptidase.
What chemical breaks up large fat droplets?
Bile
10. Bile is a substance that breaks up fat particles. Bile flows from the liver into the gallbladder, the organ that stores bile. After you eat, bile passes through a tube from the gallbladder into the small intestine.
Which enzyme is active in the phosphorylated state 1 point?
Like its own substrate, phosphorylase kinase is regulated by phosphorylation: the kinase is converted from a low-activity form into a high-activity one by phosphorylation of its β subunit.
Which enzyme converts proteins into polypeptides?
Proteolytic enzyme, also called protease, proteinase, or peptidase, any of a group of enzymes that break the long chainlike molecules of proteins into shorter fragments (peptides) and eventually into their components, amino acids.
What breaks up large fat globules into smaller droplets?
Absorption of Fats in Small Intestine: The small intestine uses bile to emulsify and break down large fat globules into smaller pieces, which allows the lipase enzymes to break down the lipids into fatty acids.
Why do small droplets of fat get broken down by enzymes more quickly than large droplets?
Protease enzyme converts proteins into amino acids. Lipase enzyme converts fats into fatty acids and glycerol. However, it emulsifies the fats, breaking it down into tiny droplets. This provides a much larger surface area for lipase enzyme to work on, so that fat is digested more quickly.
