Enzymes

Explanation:

A is wrong

An inhibitor is an addition to a catalyst that prevents it from working its full course. They make the catalyst work at a rate which is not optimal

B is correct

Enzymes are biological catalysts that speeds up the rate of biochemical reactions. They act in a way and manner in which the biochemical reactions would be slower in cases where they are not applied. They help to hasten biochemical reactions which would have been much more slower without their addition. It is necessary to add that enzymes are specific in nature. This means an enzyme that works on a particular substrate might not work on another substrate

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

where are the choice options?
