Snake venom is modified saliva that is secreted from glands on the sides of the snake's head.
Some types of venom functions by changing the shape of the enzyme cholinesterase in the
snake's prey. Cholinesterase is an enzyme that functions as a neurotransmitter that allows
the brain to control muscle movement.
What is the result of the shape change in the enzyme cholinesterase?
F The enzyme will no longer catalyze the reaction, which causes the prey to lose muscle
control.
G The substrate will change shape to match the enzyme so that the prey muscles continue
working.
H The enzyme will be capable of binding to more substrates that allow the prey to escape
the snake.
J
A new product will be made that causes the prey's muscles to not function as well as
they should.
