The concept of induced fit refers to the fact that a. Substrate binding may induce a conformational change in the enzyme, which
them brings catalytic groups into proper orientation. b. When enzymes bind substrates, the substrates are bought into proximity to make a chemical reaction favorable. c. When a substrate binds to an enzyme, the enzyme induces a loss of water from the substrate. d. When a substrate binds to an enzyme, free energy is released due to non-covalent interactions.
Option A, Substrate binding may induce a conformational change in the enzyme, which them brings catalytic groups into proper orientation.
Explanation:
Induced fit concept refers to introduction of continuous change of enzyme conformation on substrate binding. This change in the shape of enzyme either inhibit or enhance the activity of enzyme. This makes the enzyme catalytic and hence lower the activation energy thereby increasing rate of reaction.
A Fishery collapse can be defined as the condition in which the composition of different species of fishes forming a food chain or a food web and located in a marine or aquatic community undergoes a drastic alteration.
The alternation can be caused due to environmental or anthropological factors.
A fishery collapse usually affects the larger fish population like sharks and tuna as their commercial and economic demand is higher.
Excessive fishing cause the population of the large fishes to decline without affecting the small fish population.
This is because the small fishes do not have high economic or commercial demand, hence they have very less probability of being angled or captured.
