Answer:

Observe the graphic for the answer

Explanation:

1.- The first channel from left to right is the pump that exports protons, as you can observe, there are plenty of protons in the outside part, so the cell need to balance the quantity, that is the reason to be of a pump.

2.- The channel in the middle is the responsible for moving calcium, the same as the protons, from the outside part to the inside of the cell.

3.- The lactose carrier, that is the last channel, since the lactose is a carbohydrate that is quite big, needs a protein as a carrier to move it from the outside part to the inside, actually, some carriers can modify it shape as we can observe in the drawing to get inside some substances.

Hope this info is useful.

If glycogen stores are full and the body's immediate need for energy is met, what happens to the remaining glucose
lisabon 2012 [21]

The remaining glucose is converted to fat and stored into the body as an energy source.

Glucose is a sugar molecule which can be converted into two three-carbon pyruvate molecules through the process of glycolysis and then into acetyl CoA. So, when the body requires immediate energy, acetyl CoA enters the Citric Acid Cycle (Krebs cycle) and ATP is formed. But, when glucose intake exceeds your body's energy needs, acetyl CoA begins the process of fatty acid synthesis (FFA). FFAs become triglycerides that are stored in the fat tissues of the body which can be broken down later to give the energy the body needs.

Jobisdone [24]

True

Explanation:

Photosynthesis is basically a simple and natural process. Photosynthesis is defined as the process whereby green plants manufacture their food in the presence of sunlight, carbon dioxide and water.

  • The process of photosynthesis is vital to all life.
  • Through photosynthesis light energy from the sun is transformed into chemical energy.
  • The food manufactured by plants is consumed by organisms higher up in the trophic level.

                          6CO₂  + 6H₂O  →   C₆H₁₂O₆ + 6O₂

                     photosynthesis equation.

  • The product of photosynthesis is glucose and water.

Can exoskeletons break?
Harman [31]
If a large animal such as a human being had a thin light exoskeleton, there would be several problems. Since the exoskeleton would not be able to hold its shape, it would be difficult to keep the vital organs protected and the organism would be subject to damaging levels of stress just by moving around. They are not strong enough to hold organs or hold its shape.
