		Cytoplasm
		Nucleus
		Cell walls
		Mitochondria 10. Chemical energy is a form of ______________ energy, while muscle contraction is a form of ___________ energy. Autotrophic; potential Kinetic; heterotrophic Kinetic; potential Potential; kinetic Thermal; kinetic

Answer 1

6. Correct order is

glycolysis > citric acid cycle > electron transport chain

Aerobic respiration inside the cell begins with the breakdown of glucose molecules into two molecules of pyruvate. This process is known as the glycolysis. Pyruvate molecules produced during glycolysis enter into the mitochondria and get converted into acetyl CoA. Acetyl CoA participates in a series of cyclic reactions known as the Krebs cycle or citric acid cycle and generates electron carriers, NADH and FADH2. NADH and FADH2 donates their electrons to the electron carriers during electron transport chain.

7. Mitochondria

Mitochondria are double membrane enclosed cell organelles, present in all eukaryotic cells. Mitochondria generate energy in the form of ATP during the aerobic respiration. Inner mitochondrial membrane has various electron transporters that are responsible for ATP production during oxidative phosphorylation.

8. Potential; Kinetic

Chemical energy is a form of potential energy. Chemicals contain various bonds and these bonds have stored energy. During muscle contraction energy is supplied by the ATP molecules and chemical energy of ATP molecules gets converted into the kinetic energy during muscle contraction.
