Explanation:
When enzyme does not work properly it is said to be inactive and this affect its efficiency.
Substrate concentration - Enzyme requires adequate substrate concentration to be effective, when the concentration is high the enzyme activity increases and when it is low it decreases.
Temperature - Enzymes are more active at specific temperature at very high temperature enzyme can be denatured leading to a loss of its activity. Hence, enzyme should be made to work at its optimum.
pH- Enzymes are active at specific pH, when the pH is altered enzymatic activity may be reduced or enzyme become inactive. Hence, pH of enzymes should be maitained.
The epithelium with a single layer of tall cells is classified as simple cuboidal epithelium.
Epithelium is one of the major types of body tissue that line the outer surfaces of organs and blood vessels throughout the body.
The epithelium performs the following functions that include:
- protection,
- secretion,
- secretion, absorption,
- excretion,
- filtration,
- diffusion, and
- sensory reception.
There are also different types of epithelium found in different parts of the body. A typical example is the simple cuboidal epithelium.
Simple cuboidal epithelium are single layered epithelium that are as tall as they are wide (cuboidal in shape).
They are found lining areas that are active in secretion and absorption.
Therefore, the epithelium with a single layer of tall cells is classified as simple cuboidal epithelium.
