All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate, protein, or fat, that the enzyme is designed to breakdown. There are a number of different enzymes in the human body; each type produced ...
Why are enzymes specific? Why is acetyl-CoA not a gluconeogenic precursor? Why do lipids make effective cell membranes in living cells? Why will external fluid flow into a plant cell? Why is ATP a high energy molecule? Why do red blood cells get denucleated?
Make a drawing or describe an enzyme and substrate, enzyWhy are enzymes so specific?Why do enzymes act only on very specific substrates?Describe two important features that make all enzymes catalysts.Why aren't enzymes used more often for drug synthesis?
Little information has been reported on expression of NAT genes during embryonic and fetal development although substrate specific NAT activity has been detected. The current study investigated the expression of NAT1 and NAT2 in mice pre-and postnatally. RNA was isolated from maternal liver, ...
2'N acetyltransferase, which may inactivate bacterial peptidoglycans is able to inactivate Gentamicin it has a structure similar to the original action of the enzyme substrate. Penicillins and ß-lactams derivatives covalently binds a specific set of bacterial proteins - Penicillin- Binding-Proteins ...
Why are enzymes so specific? Why enzyme action is considered highly specific? Why can't an enzyme that hydrolyzes starch degrade cellulose? Explain why a particular enzyme will only fit with one particular type of substrate. Why is co-enzyme A so unique to our metabolism? What is an ...
molecule. Ubiquitination via the proteome can mark proteins for degradation. It is also important for cellular signaling, the internalization of membrane proteins , and the development and regulation of transcription. Ubiquitin can be removed from proteins by...
2. Protein tyrosine phophatases and protein tyrosine kinases are immune cell gatekeepers Protein Tyrosine Phosphatases (PTPs) and Protein Tyrosine Kinases (PTKs) are enzymes that specifically catalyse the reversible addition or release of phosphate groups from tyrosine residues on signalling intermediates....
Why are enzymes important for living organisms? Why is there little or no digestion of starch in the stomach? Explain what could happen to the effectiveness of pancreatic enzymes in the small intestine if bile is not available. Explain why a reactant is also called the "substrate" when it ...
What is the substrate that catalase reacts with? What is the importance of water for enzyme activity? What is an enzyme and why are enzymes crucial in carrying out chemical reactions in the cell? How do factors such as temperature and pH affects the rate of enzyme activity, such as that ...
