When the active site has a rigid shape it is called the lock and key model where substrate is key which fits
the lock of active site
lock and key model is not used to explain why certain enzyme catalyses wide variety of substrate reaction in fact
this model explain the specific nature of enzyme catalysed reaction where if and only if key of substrate fits the lock
of active site biochemical reaction takes place
Enzymes are essential to human body because the kind of biochemical reaction enzymes catalysed in side human body
which essential to survive will take place at very harsh and extreme temperature and pressure condition without those enzymes

Biology help please. 1) Draw the 4 step process of an enzyme reacting with a substrate. LABEL the enzyme, the substrate, and the active site. 2) What is it meant by the phrase lock and key fit? Explain. What is induced fit? Explain. 3) Are enzymes generic or specific (i.e. can an enzyme catalyze any reaction, or only a specific reaction)? Explain why? Thanks

1 point Nicotinamide adenine dinucleotide (NAD+) is an essential cofactor for many metabolic reactions. Lack of the precursor to NAD+, niacin, results in the human disease called pellagra, thus humans have evolved salvage pathways to breakdown and re-synthesize NAD+ when needed. Below is the chemical structure of NAD+. Enzymes catalyze reactions in parts of the protein called an active site. This portion of the protein forms favorable weak interactions with the substrate and stabilize the transition state, which is crucial...
