Phototropism is of two types :-

1-Positive Phototropism - In this type of phototropism plants move or grow towards the light source.

Sunflowers are most common example of positive phototropism.

2- Negative Phototropism - In this type of phototropism plants move or grow in opposite direction of the light source.

Andre45 [30]

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.
