Q? Describe the concentration gradient of carbon dioxide across the cell membrane.
hoa [83]

Answer:

Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.

Explanation:

CO_{2} undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.

Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.

Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.

Anna007 [38]
I believe increased blood pressure indicates the presence pf pheochromocytoma. The increased blood pressure could be due to the increased production of catecholamines, indicating a lack of balance in the endocrine.  Pheochromocytoma is a neuroendocrine tumor of the medulla of the adrenal glands or extra-adrenal chromaffin tissue that failed to involute after birth, that secretes high amounts of catecholamines (norepinephrine or epinephrine).
