Answer: Water moved from inside the red blood cell into the salt water.
This is because of the osmotic difference between the salt solution and the red blood cell. This means that there is difference in the solute (salt) concentration inside the red blood cell and the salt solution.
Explanation: The salt concentration in the solution is higher than the salt concentration inside the red blood cell, that is, the red blood cell has more water concentration that the salt solution, therefore there will be movement of water from the inside of the red blood cell into the salt solution thereby causing the red blood cell to reduce in size. The movement of water from the red blood cell into the salt solution is to create a balance between the water concentration in the two environments, hence the movement of water from an area of high water concentration to an area of low solvent concentration across the selectively permeable membrane of the red blood cell.
A) positive ion and a negative ion
Answer:
Light
Explanation:
Photosynthesis is the process of turning light into energy
the first signs appear in the stage of resistance
Phosphoglycerate kinase does not catalyze an irreversible process in glycolysis under normal cellular circumstances.
Discussion about glycolysis:
- Ten stages make up the glycolysis process, seven of which are reversible and three of which are practically irreversible. These are the first, third, and final stages that are successively catalyzed by hexokinase, phosphofructokinase, and pyruvate kinase.
- During the glycolysis process, glucose 6-phosphate is changed into pyruvate. Everything that happens is cytoplasmic. Fructose 6-phosphate is created by reversible isomerization of glucose 6-phosphate. Physiologically irreversible fructose 6-phosphate phosphorylation to fructose 1,6-bisphosphate is performed by phosphofructokinase.
Hexokinase, phosphofructokinase-1, and pyruvate kinase conduct nearly irreversible events during glycolysis, hence one would anticipate that these enzymes have both regulatory and catalytic functions.
So, option d i.e., phosphoglycerate kinase should be the appropriate response.
