Answer = 0°C
QUESTION 9
Which of the following is NOT true for a competitive inhibitor?
Answer = It binds to the enzyme at a site remote from the active site.
TRUE: It occupies the active site; It cannot be converted to products; It has a structure similar to the substrate; Increasing the substrate concentration can reverse competitive inhibition.

Answer = heart attack
Lipases perform fundamental parts in the assimilation, transport and handling of dietary lipids (e.g. triglycerides, fats, oils) in most, if not every, living life form. Qualities encoding lipases are even present in certain infections.
Most lipases act at a particular position on the glycerol spine of a lipid substrate (A1, A2 or A3)(small digestive system). For instance, human pancreatic lipase (HPL), which is the principle protein that separates dietary fats in the human stomach related framework, changes over triglyceride substrates found in ingested oils to monoglycerides and two unsaturated fats.
====================
Lactate dehydrogenase (LDH or LD) is a compound found in almost all living cells (creatures, plants, and prokaryotes). LDH catalyzes the change of lactate to pyruvic corrosive and back, as it believers NAD+ to NADH and back. A dehydrogenase is a protein that exchanges a hydride starting with one particle then onto the next. LDH exist in four particular catalyst classes. This article is particularly about the NAD(P)- subordinate L-lactate dehydrogenase. Different LDHs follow up on D-lactate as well as are subject to cytochrome c: D-lactate dehydrogenase (cytochrome)) and L-lactate (L-lactate dehydrogenase (cytochrome)).
===============================================================================
A hexokinase is a compound that phosphorylates hexoses (six-carbon sugars), framing hexose phosphate. In many living beings, glucose is the most essential substrate of hexokinases, and glucose-6-phosphate is the most critical item. Hexokinase additionally, as researchers have found and illustrated, posesses the ability to play out the capacity of exchanging an inorganic phosphate assemble from ATP to a substrate.
=================================================================================
Hexokinases ought not be mistaken for glucokinase, which is a particular isoform of hexokinase. While different hexokinases are equipped for phosphorylating a few hexoses, glucokinase acts with a 50-crease bring down substrate partiality and its exclusive hexose substrate is glucose.
