Which statement describes all enzymes?
|
|
They control the transport of materials.
|
|
|
They provide energy for chemical reactions.
|
|
|
They affect the rate of chemical reactions.
|
|
|
They absorb oxygen from the environment.

Explanation:
Detailed explanation-1: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.
Detailed explanation-2: -Answer and Explanation: Enzymes are proteins that speed up chemical reactions.
Detailed explanation-3: -Enzyme activation energy Enzymes are similar to other chemical catalysts. They participate in the reaction without getting affected. In other words, they speed up the chemical reactions inside the cells without getting consumed. Enzymes are affected by the hydrogen ion concentration (pH) and the temperature.
