Answer:

the humus contains the minerals necessary for chlorophyll synthesis

Explanation:

<em>The yellowness of leaves in plants can be attributed to inadequate chlorophyll in the plant</em>. The chlorophyll is responsible for the greenness appearance of the leaves of plants and when it is present in inadequate quantity, the leaves appear yellowish in color.

<u>Some of the minerals necessary for the formation of chlorophyll include magnesium, nitrogen, and iron</u>.

Varvara68 [4.7K]

Answer:

There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding

Explanation:

An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.

Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding.
