The lock-and-key mechanism refers to a) the complementary shapes of an enzyme and a substrate. b) the attractive forces between
an enzyme and a substrate. c) the ability of an enzyme to lower the activation energy of a reaction. d) the ability of an enzyme to “unlock” the products of a reaction.
A. The complementary shapes of an enzyme and a substrate
Explanation:
The Lock-and-Key model was made to show how an enzyme's active zone fits a substrate and how they bond together. It correlates just like a lock and a key; you have to have the correct-shaped key in order to open a lock. Same process of thought with the enzymes; you must have the same shape for both in order to bind together,
I would love to answer this question for you, sadly you have not provided us with the diagram. So I am not able to see which type of plant experienced a drought.
Id say that the best answer is Loess. I say that cause loess means a loosely compacted yellowish-gray deposit of windblown sediment of which extensive deposits occur.
