Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.

The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells. Inside, carbonic anhydrase converts carbon dioxide into carbonic acid (H2CO3), which is subsequently hydrolyzed into bicarbonate (HCO3−) and H+. The H+ ion binds to hemoglobin in red blood cells, and bicarbonate is transported out of the red blood cells in exchange for a chloride ion. This is called the chloride shift.

Bicarbonate leaves the red blood cells and enters the blood plasma. In the lungs, bicarbonate is transported back into the red blood cells in exchange for chloride. The H+ dissociates from hemoglobin and combines with bicarbonate to form carbonic acid with the help of carbonic anhydrase, which further catalyzes the reaction to convert carbonic acid back into carbon dioxide and water. The carbon dioxide is then expelled from the lungs.

Give an example of mechanical and chemical digestion?

Karo-lina-s [1.5K]

Answer:

Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells.

Explanation:

Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.

JulsSmile [24]

Answer:

Pulmonary fibrosis is a disease that affects the lungs. The lung tissue becomes damaged and scarred which causes it to be thickened and stiff.

The condition pulmonary fibrosis is caused by the replacement of elastic fibers in the lung with inelastic collagen fibers. This decreases the lungs’ ability to stretch outwards.

Pulmonary fibrosis however mainly affects inspiration because the lungs cannot stretch to increase volume while during expiration stretching of the tissues doesn’t happen so it doesn’t affect the process.

A six-carbon sugar is an example of a ______ that can join with other molecules to form a _____ such as starch or cellulose

Alexxandr [17]

<span>The answer is: molecule; carbohydrate. A six-carbon sugar is an example of a molecule that can join with other molecules to form a carbohydrate such as starch or cellulose. The basic unit of carbohydrate is monosaccharide. A six carbon sugar would be an example of a monosaccharide. And it can join with other simple sugars (monosaccharides) to form polysaccharides, such as starch or cellulose.</span>
