The statement which best explains why Pepsin will not break down starch is that enzymes only work for specific substrates.
<h3>
What is an Enzyme?</h3>
This is referred to as a biological catalyst which helps to speed the rate of chemical reaction in the body by lowering the activation energy needed to start it up. it is also proteinous and can be denatured by heat and other substance such as chemicals.
They are also substrate specific which means they can't act on any type of substance. For example enzyme such as amylase acts on only starch while pepsin acts on only protein.

For most athletes, the period in their
yearly training cycle during which it is recommended to begin calorie restriction
so as to lose significant amounts of stored body fat is the off-season or early
in the preseason. Restriction of energy intake late in the preseason when
there is rigorous training or during season when there is competition may impede training, recovery,
or performance.
Because, photoautotrophs serves as their carbon sources.
Chemoheterotrophic bacteria are those bacteria that are incapable of producing their own food, they depend on photoautotrophs, which are capable of making their own food by trapping energy from the sun. Thus, photoautotrophs serves as source of food for the chemoheterotrophic bacteria.
Biochemistry is the study of the chemical processes occurring in living matter.
Transmembrane proteins are found in the plasma membrane. Hydrophilic regions are embedded
<span>
within the membrane, and Hydrophobic regions project from both surfaces of the bilayer.

Approximately 20-80% of the cell membrane is composed of lipids, the rest, is made up of protein. The lipid layer of the membrane gives it flexible and permeable characteristic. While the protein part assists in transport of molecules it needs to survive.<span>
