Answer:
The circulatory and respiratory systems interact to transport carbon dioxide to the lungs, where it is expelled from the body.
Explanation:
Carbon dioxide produced by the cells and tissues during cellular respiration is removed from the body through the interaction of the circulatory and respiratory system. The medium of transport of carbon dioxide is the blood which carries to the lungs, where it is expelled from the body in ordernto maintain homeostasis in the body.
Carbon dioxide molecules are transported in the blood from body tissues to the lungs in three ways:
1. Dissolution directly into the blood - due to its greater solubility in blood than oxygen, carbon dioxide is dissolved in blood plasma. On reaching the lungs, it leaves the blood by diffusion and is then expelled out of the body.
2. Binding to hemoglobin - carbon dioxide binds reversibly with haemoglobin in the red blood cells to form a molecule called carbaminohemoglobin. When it reaches the lungs, the carbon dioxide freely dissociate from the hemoglobin and is expelled from the body.
3. Carried as a bicarbonate ion - the majority of carbon dioxide molecules are carried as part of the bicarbonate buffer system. In this system, carbon dioxide diffuses into the red blood cells. The enzyme carbonic anhydrase within the red blood cells quickly converts the carbon dioxide into carbonic acid (H2CO3) which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ions leaves the red blood cells in exchange for chloride ions in the plasma. The bicarbonate ions then travel in plasma to the lungs, where they enter the red blood cells again. It combines with hydrogen ions from the haemoglobin to form carbonic acid. Carbonic anhydrase breaks carbonic acid down into water and carbon dioxide which is then expelled from the lungs.
Although glycolysis produces four molecules of atp by substrate-level phosphorylation, the net gain of atp for the cell is two molecules. This is because glycolysis is at first endergonic.
<h3>
What is glycolysis?</h3>
- The metabolic process that turns glucose into pyruvic acid is known as glycolysis.
- The high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process.
- A series of ten enzyme-catalyzed processes make up glycolysis.
- The process by which glucose is broken down to provide energy is known as glycolysis.
- It generates two pyruvate molecules, ATP, NADH, and water.
- There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell.
- Both aerobic and anaerobic creatures experience it.
- The initial process in breaking down glucose to release energy for cellular metabolism is called glycolysis.
- An energy-consuming phase and an energy-releasing phase make up glycolysis.

<span>The right option is <span>B) Combination of all the wavelengths of visible light
</span><span>White light is formed when there is mixture of all the colors of the visible light spectrum (ROYGBIV). White light is perceived when all the wavelengths of the visible light spectrum strike the eye at the same time. The sensation of white is not the result of a single color of light.
