Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The breakdown of ____ supplies immediate, quick energy for all cell activities.
A
carbohydrates
B
lipids
C
proteins
D
nucleic acids
Explanation: 

Detailed explanation-1: -Your body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body’s cells, tissues, and organs. Glucose can be used immediately or stored in the liver and muscles for later use.

Detailed explanation-2: -Carbohydrates can be used as an immediate source of energy by largely all cells, but in many photosynthetic organisms a major portion of the carbohydrates will be used for production of structural compounds, e.g., cellulose in cells walls, or for synthesis of storage products such as starch.

Detailed explanation-3: -Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. In cellular respiration sugar with the help of oxygen is broken down into ATP (energy molecule).

Detailed explanation-4: -The immediate source of energy for most cells is glucose. But glucose is not the only fuel on which cells depend. Other carbohydrates, fats and proteins may in certain cells or at certain times be used as a source of ATP.
