Answer:
A.
Explanation:
Bc the rest are not reasonable
Answer:
A proton Pump, using ATP, pumps protons outside
A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
pH decreases;
The gradient becomes sufficient.
H+ moves down electrochemical gradient into the cell; Sucrose moves into the cell.
Explanation:
A proton Pump, using the energy of ATP hydrolysis, pumps protons outside the cell.
A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
The continues outward pumping of protons by the proton pump causes the pH of the extracellular fluid to decrease
At some point the gradient becomes sufficient, and pH reaches a steady slightly acidic level.
H+ moves down its electrochemical gradient into the cell together with Sucrose through the hydrogen ion-sucrose co-transporter.
Answer:
Vascular tissue is responsible for transporting water, mineral and sugar to differnt parts of the plant
Explanation:
Answer:
converted into fat and stored in adipose tissue
Explanation:
When protein is taken in excess amount, because it cannot be stored in the body, it can be broken down to amino acids, which is further used as carbon skeletons to synthesize fats, which is then further stored in the adipose tissues.
When the body is not receiving enough calories from other nutrient sources like carbohydrates and fats, the available protein is the used as energy to meet the body's energy demands, by converting it to fat.
Note that, excess intake of protein can be harmful to the body.
