Q4: What is Respiration?

Let's tackle the remaining questions from the image.

Q4: What is Respiration?
Respiration is the process by which living organisms break down glucose (sugar) to release energy for their metabolic activities. This process typically consumes oxygen and produces carbon dioxide and water as byproducts.

Q5: Write the word equation for respiration
The word equation for respiration is:
Glucose + Oxygen → Carbon dioxide + Water + Energy

Q6: Write the Chemical Equation for respiration
The chemical equation for respiration is:

$$\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{Energy}$$

Q7: Why is it appropriate to say that Photosynthesis and Respiration are opposites of each other?
Photosynthesis and respiration are considered opposite processes because their inputs and outputs are largely reversed, and they have opposing effects on energy. Photosynthesis uses carbon dioxide, water, and light energy to produce glucose and oxygen, thereby storing energy. Respiration, on the other hand, uses glucose and oxygen to produce carbon dioxide, water, and chemical energy (ATP), thereby releasing energy.
