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.
Hello User,
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
- Living things are made of cells. Cells are the basic building blocks of living things
- Living things have movement. This movement can be quick or very slow.
- All living things have a metabolism
Answer:
Okay so start with diagramming the phases of Mitosis (interphase, prophase, metaphase, anaphase, telophase, cytokinesis) then draw what all the phases would look like for a plant cell. You can search what a plant cell looks like in mitosis and use it as a reference.
Explanation:
the color coding is for drawing each thing in the phases of mitosis
Answer: Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others. The capacity to filter molecular transport in this manner is called selective permeability.
Explanation:
Shortened: This means the membrane only allows some things to pass through while others can't.
Hope this helps! ^^
D. Homozygous dominant because the dad has the dominant allele.
