Question

(a) Mention the cell organelle shown in the diagram.

(b) Which energy rich molecules are synthesised during Kreb’s cycle?

(c) Identify the compound ‘X’ which is a product of glycolysis, that is

utilized in Kreb’s cycle.​

Answer 1

Answer:

a)mitochondria

b)ATP,NADH,FADH2

c)pyruvicacid

Explanation:

Answer 2

(a) The cell organelle shown in the diagram is mitochondria.

(b) NADH and flavin adenine dinucleotide (FADH2), also some ATP is synthesized.

(c) The compound ‘X’ which is a product of glycolysis is pyruvic acid.

• The Krebs cycle, also referred to as the TCA cycle or the citric acid cycle, is a series of chemical processes that take place in the mitochondria and are essential for aerobic breathing, the process by which almost all living things generate energy.
• It consumes oxygen and produces water and carbon dioxide as waste.
• There are two crucial purposes for the Krebs cycle.
• Production of intermediate molecules, which are crucial for the synthesis of substances like amino and fatty acids, is one.
• The other is the production of a lot of ATP, which supplies power for different synthetic processes.
• Every organism that produces energy from oxygen contains the Krebs cycle.
• This metabolic route is utilized both when catabolism is present and as an anabolic cellular principle.
