inna [77]

Answer:

The minerals will not be move or transported to other part of the plants because active transport require energy.

Explanation:

Active transport is a process where molecules and ions are move against a concentration gradient by using energy.

This process require energy, for ions or molecules of minerals to be taken up by plants, it is first moved to the root hairs where they are in high concentration against in dilute concentration on soil Active Transport then occur in the roots where it is taken up to the plants with the use of energy.

If there is not enough energy, active transport will not occur and the minerals will remain in the root hair and will not be move to other part of the plant.

What percentage of the energy stored in glucose do humans recover by cellular respiration?
Nady [450]
  • Energy is generated by glyolysis and aerobic respiration which contributes to approximately 252kcal. This is only 37% of total energy of glucose i.e 686kcal/mol.
  • According to the second law of thermodynamics all of the energy cannot  be converted into work done i.e most of the energy is lost in the form of heat.
  • So, there 63% of the energy present in glucose is lost in the form of heat and 37% of the total energy is used for cellular respiration
