Photosynthesis and Respiration - 1 (Class IX)

This is the correct option as release of ATP is not included in light reactions. 

This is the correct option. Glycolysis occurs in the cytoplasm of a cell.

This is the correct option as this statement is false. In anaerobic respiration, the organisms break down the food into carbon dioxide and ethanol.

This is the correct answer as ethanol, carbon dioxide and energy are produced during anaerobic respiration.

Carbon dioxide is converted into sugars in a process called carbon fixation.

Acetyl CoA is not formed during anaerobic respiration. 

Mesophyll cells, along with palisade and spongy cells, in a leaf are the principal centres of photosynthesis.

There are some organisms such as yeast that can survive in the absence of air. They are called anaerobes. They get energy through anaerobic respiration. In the absence of oxygen, glucose breaks down into alcohol and carbon dioxide.

Dark reaction of photosynthesis utilises CO₂. Dark reactions make use of organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy, while NADPH provides the electrons required to fix the CO₂ (carbon dioxide) into carbohydrates.
