Select the statements that are true. Question 1 options: CO2 and O2 are water-soluble molecules that diffuse freely across cell
lidiya [134]

Answer:

CO2 and O2 are water-soluble molecules that diffuse freely across cell membranes.

Cells expend energy in the form of ATP hydrolysis so as to maintain ion concentrations that differ from those found outside the cell.

Explanation:

CO2 and O2 are highly soluble molecules in water due to their polarizability and their ability to react with water molecules and form new compounds. CO2 is 30 times more soluble in water than oxygen, which also has a high solubility. This ability allows these two molecules to diffuse freely across cell membranes.

Cells promote hydrolysis, that is, the breakdown of ATP molecules when they need to expend energy for any metabolic process, especially when they need to maintain a balance between ion concentrations inside and outside the cell. This is because ATP is a highly energetic molecule and its breakdown promotes energy for the cell to use in its activities.

Which of the following is the correct description of a myocardial infarction and what it is caused by? View Available Hint(s) Wh
Luda [366]
<h2>The answer that is correct is the: Third statement.</h2>

Explanation:

  • Heart is one of the most essential organ in the human body as it is responsible for supplying nutrients and oxygen to all the parts of the body and  collecting waste materials and carbon dioxide from all the parts of the body through the blood.
  • The cells (fibroblasts, cardiomyocytes, etc.) of the heart itself are provided with the nutrients and oxygen by a specialized blood vessel called the Coronary Artery.
  • Waste materials and carbon dioxide are removed from the cells of the heart by another specialized blood vessel called the Coronary Vein.
  • Due to aging or consumption of excess fat and cholesterol rich food, the concentration of lipid molecules in blood get increased beyond normal.
  • These lipid molecules get deposited in the walls of the arteries, including the coronary artery, forming plaques, resulting in the development of atherosclerosis.
  • This reduces the diameter of the arteries, including the coronary artery, thereby reducing the blood flow through them.
  • Due to plaque deposition, the coronary artery is incapable for carrying sufficient oxygen and nutrients to the heart cells, causing their death.
  • This results in the development of a sharp pain in the chest that is diagnosed as Heart Attack or Myocardial Infarction.
