Answer:
The correct answer is option c. "Enzyme lowers the activation energy".
Explanation:
The activation energy is defined as the amount of energy needed for a reaction to take place. Enzymes catalyze reactions by lowering the activation energy, which speeds up the reaction and increases its rate. Enzymes put a substrate in its active site, which facilitates the reaction and makes more likely that it collides with its subsequent substrate.
Answer:
Great relationship.
Explanation:
There is a great relationship between the structure and functions of animal cells because the structure of cells helps the cell to perform a particular function assign to it. The cells in epithelial tissue are tightly packed together with a very little intercellular matrix. intercellular matrix is a non-living material used to fill the spaces between the cell. Due to this structure, the epithelial tissue forms the covering of all body and helps in protecting the skin.
