Question

fig 4.1 is an incomplete flow chart of the process of anaerobic respiration in yeast and in muscles.
complete fig to show the substrate and products for anaerobic respiration in yeast and in muscles. (4)​

Answer 1

Under anaerobic condition, yeasts produces ethanol and carbon dioxide, while muscles produce lactic acid, provided the substrate is glucose.

Explanation:

Respiration:

The process by which a living organism produces energy by breaking down molecules such as glucose with or without the help of oxygen.

Respiration can be expressed simply in the form of an equation:

Substrate + Oxygen → Energy

Types of respiration:  

Based on the presence or absence of oxygen, respiration can be classified into:  

1. Aerobic: in the presence of oxygen
2. Anaerobic: in the absence of oxygen

In the given question, substrate undergoes anaerobic respiration and gives products. Assume, the substrate to be glucose.

In yeast:

C₆H₁₂O₆ (glucose) → C₂H₅OH+CO₂ (ethanol + carbon dioxide) + energy

In muscles:

C₆H₁₂O₆ (glucose) → 2C₃H₆O₃ (lactic acid) + energy
