Respiration - 2

RQ indicates nature of respiratory substrate.It is the ratio of the volume of carbon dioxide evolved to that of oxygen consumed by an organism, tissue, or cell in a given time.

Malic acid has the highest RQ and its value is 1.33.

Respiratory roots are found in jussiaea.These roots are white and spongy filled with air that keep plants floating.

The sum total of all reactions occurring in the body, whether constructive or destructive is known as metabolism.

Yeast can respire in the absence of oxygen and it produces alcohol as a by-product.

The number of ATP molecules produced during aerobic and anaerobic respiration are 38 and 2, respectively.

The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth.

A person respires around 16 - 20 times in a minute.

Option (4) is the correct answer.

During inspiration (breathing in), the diaphragm contracts, drawning downward, creating a vacuum in the thoracic cavity. This vacuum inflates the lungs by drawing air into the body through the trachea, or windpipe.

In reptiles, respiration takes place through skin. It is known as cutaneous respiration.

Exchange of gases in lung alveoli occurs through simple diffusion,O2 diffusing from the alveoli into the blood & CO2 from the blood into the alveoli.

Acetyl-CoA is not formed during anaerobic respiration.Anaerobic respiration is a form of respiration using electron acceptors other than oxygen.

Photosynthesis is complementary to respiration.as the products of one reaction are the reactants of another.So, cellular respiration consumes sugars and oxygen and creats carbon dioxide, water, and releases energy. Photosynthesis combines energy, carbon dioxide, and water to form sugar and oxygen.

Energy released during respiration is stored in the form of ATP.It transports chemical energy within cells for metabolism.

Loss of hydrogen is caused by the biological oxidation of respiratory substrate.

In the human body, fats are stored in adipose tissue. Its main role is to store energy in the form of lipids, although it also cushions and insulates the body.

Aerobic respiration is more advantageous than anaerobic respiration because it produces more energy.

Pneumatophores are called breathing roots. These are the roots found above the ground.

Cytoplasm is the site of glycolysis, which is the breakdown of glucose by enzymes, releasing energy and pyruvic acid.
