NEET BIOLOGY

Detailed explanation-1: -Statement 1: During respiration, humans and animals take in carbon dioxide and release oxygen. Statement 2: During photosynthesis, plants utilise carbon dioxide and release oxygen.

Detailed explanation-2: -CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation. CO2 plays various roles in the human body including regulation of blood pH, respiratory drive, and affinity of hemoglobin for oxygen (O2).

Detailed explanation-3: -The word respiration is commonly used to describe the process of breathing in oxygen and breathing out carbon dioxide. However, the term more formally refers to the chemical process organisms use to release the energy from food, which typically involves the consumption of oxygen and release of carbon dioxide.

Detailed explanation-4: -CO2 is the fourth most abundant gas in the earth’s atmosphere. At room temperature, carbon dioxide (CO2) is a colorless, odorless, non-flammable gas, at other temperatures and pressures, carbon dioxide can be a liquid or a solid.

Detailed explanation-5: -Carbon dioxide is a waste byproduct of cellular respiration. This is removed out of the body by the. Q. All plants and animals respire by reducing carbohydrates in their cells to produce energy and give out carbon dioxide into the atmosphere.
