$\Huge{\textbf{Answer:}}$

→ $\blue{\textbf{What is Respiration?}}$

• All living organisms need a constant supply of energy.

• Respiration is the process of releasing energy through the breakdown of nutrients such as glucose.

• Respiration can be aerobic or anaerobic.

• Aerobic respiration takes place continuously in both plants and animals.

→ $\blue{\textbf{How Does It Occurs?}}$

• It occurs through a process known as cellular respiration.

• It is of 2 types:

→ $\green{\textbf{Aerobic Respiration:}}$

• Aerobic respiration uses oxygen to break down glucose.

• Aerobic respiration can be described as the process of releasing energy through the oxidation of glucose molecules.

• Aerobic respiration releases lots of energy from each glucose molecule by breaking it down completely into carbon dioxide and water.

→ $\green{\textbf{Anaerobic Respiration:}}$

• Anaerobic respiration takes place without oxygen.

• Anaerobic respiration is the incomplete breakdown of glucose.

• This process releases much less energy per glucose molecule than aerobic respiration and produces lactic acid.

• Anaerobic respiration occurs when cells have insufficient oxygen for aerobic respiration to occur.
