Answer:
The lock-and-key model:
c. Enzyme active site has a rigid structure complementary
The induced-fit model:
a. Enzyme conformation changes when it binds the substrate so the active site fits the substrate.
Common to both The lock-and-key model and The induced-fit model:
b. Substrate binds to the enzyme at the active site, forming an enzyme-substrate complex.
d. Substrate binds to the enzyme through non-covalent interactions
Explanation:
Generally, the catalytic power of enzymes are due to transient covalent bonds formed between an enzyme's catalytic functional group and a substrate as well as non-covalent interactions between substrate and enzyme which lowers the activation energy of the reaction. This applies to both the lock-and-key model as well as induced-fit mode of enzyme catalysis.
The lock and key model of enzyme catalysis and specificity proposes that enzymes are structurally complementary to their substrates such that they fit like a lock and key. This complementary nature of the enzyme and its substrates ensures that only a substrate that is complementary to the enzyme's active site can bind to it for catalysis to proceed. this is known as the specificity of an enzyme to a particular substrate.
The induced-fit mode proposes that binding of substrate to the active site of an enzyme induces conformational changes in the enzyme which better positions various functional groups on the enzyme into the proper position to catalyse the reaction.
Answer:
dentifying genetic variants Genome sequencing has the potential to improve the diagnosis of conditions caused by changes in the DNA and indicate what treatments may be most effective. Importantly, it may also red-flag treatments likely to cause adverse reactions.
Explanation:
Atomic physics is the field of physics that <span>studies atoms.
</span>In 1913, Niels Bohr made a theory for the hydrogen atom based on quantum theory which states<span> that energy can only be transferred in certain quantities. Electrons move around the nucleus but only in fixed orbits. When an atom jumps from one orbit to another with lower energy level, a light quantum is emitted as a result.</span>
