The approximate amount of CO2 in our exhaled air is [D] 16%. Exhaled air contains a higher concentration of carbon dioxide compared to inhaled air because CO2 is a waste product of cellular respiration. While inhaled air typically contains about 0.04% CO2, exhaled air can have concentrations ranging from 3-5%, depending on factors such as metabolism, respiratory rate, and environmental conditions. During cellular respiration, cells use oxygen and glucose to produce energy, releasing CO2 as a byproduct. This CO2 is transported via the bloodstream to the lungs, where it diffuses into the alveoli and is then exhaled during expiration. The higher concentration of CO2 in exhaled air reflects the metabolic activity occurring within the body and provides a means for the removal of this waste gas from the bloodstream.
The complete conversion of sucrose into CO2 and water in the presence of oxygen with the release of energy is called [A] Aerobic respiration.

The complete conversion of sucrose into CO2 and water in the presence of oxygen with the release of energy is called [A] Aerobic respiration. Aerobic respiration is a cellular process that occurs in the presence of oxygen, involving the breakdown of organic molecules such as sucrose (a disaccharide) into carbon dioxide (CO2) and water (H2O) while releasing energy in the form of ATP (adenosine triphosphate).
This process consists of multiple stages, including glycolysis, the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation, which occurs in the mitochondria. Aerobic respiration is highly efficient, producing a large amount of ATP per molecule of sucrose compared to anaerobic respiration. It is the primary energy-generating process in most eukaryotic cells, providing the necessary energy for cellular functions and metabolic activities.

The conversion of food into energy takes place in [D] Mitochondria. Mitochondria are specialized organelles found in eukaryotic cells responsible for cellular respiration. During cellular respiration, glucose and other organic molecules undergo a series of biochemical reactions in the mitochondria to produce ATP (adenosine triphosphate), the primary energy currency of the cell. This process involves the citric acid cycle (Krebs cycle) and oxidative phosphorylation, which occur within the mitochondrial matrix and the inner mitochondrial membrane, respectively.
Mitochondria are often referred to as the “powerhouses” of the cell due to their role in generating ATP through the oxidation of food molecules. This energy is then utilized by the cell for various metabolic processes, including growth, maintenance, and cellular activities such as muscle contraction, nerve signaling, and biosynthesis.

A human being typically breathes [B] 20-25 times in a minute. This respiratory rate, known as the respiratory or breathing rate, refers to the number of breaths taken within one minute. It is influenced by various factors including age, physical activity level, health status, and environmental conditions. At rest, adults generally breathe within the range of 12-20 breaths per minute, while infants may have a higher respiratory rate. During periods of physical exertion or stress, the respiratory rate may increase to meet the body’s demand for oxygen. Conversely, during sleep or periods of relaxation, the respiratory rate tends to decrease. The normal range of 20-25 breaths per minute represents an average value for adults at rest and is considered within the typical physiological range for respiratory frequency.
Deficiency of Vitamin A is the main cause of night blindness. This condition, medically known as nyctalopia, occurs due to the impaired function of the retina, affecting the ability to see in low light conditions.

Deficiency of Vitamin A is the main cause of night blindness. This condition, medically known as nyctalopia, occurs due to the impaired function of the retina, affecting the ability to see in low light conditions. Vitamin A plays a crucial role in maintaining healthy vision, particularly in the adaptation of the eyes to darkness. Without sufficient Vitamin A, the production of rhodopsin, a pigment necessary for low-light vision, is compromised, leading to night blindness. Thus, ensuring an adequate intake of Vitamin A-rich foods such as carrots, spinach, sweet potatoes, and liver can help prevent this deficiency and maintain optimal eye health.
