25 point question! asap! will give brainliest to correct a) the pathway a-b-d involves a catalyst and is slower than a-c-d. b) the pathway a-b-d involves a catalyst and is faster than a-c-d. c) the pathway a-c-d involves a catalyst and is slower than a-b-d. d) the pathway a-c-d involves a catalyst and is faster than a-b-d.

D

Explanation:

A catalyst functions to speed up chemical reaction. It does this by lowering the activation energy required for the reaction to begin by providing an alternative pathway for the substrates to interact with each.

The pathway ABD involves a reaction that requires a higher activation energy as compared to reaction following the pathway ACD as seen in the diagram.

So it means that a catalyst must be mediating the reaction with the lower activation energy. -pathway ACD, and this reaction will proceed faster than the reaction following the pathway ABD.

Hence option D is the only valid and correct option.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
