Answer:

In daylight calvin cycle occurs, in darkness Calvin cycle occurs along with conversion of CO2 into sugar and in extended darkness Calvin cycle stops

Explanation:

During daylight, Calvin cycle takes place within the stoma. In this process, energy obtained from sun is converted and stored into bio molecules namely ATP and NADPH.  

During darkness, Calvin cycle takes place but the energy of biomolecules i.e ATP and NADPH is used to convert carbon dioxide into sugar. Prolonged exposure to darkness causes reduction in production of energy molecules. Also, the Calvin cycle stops in extreme darkness for a long period of time.

Effectus [21]

Answer: D. Digestion increases as the volume of the enzyme increases.

Explanation:

Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster.

Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.

(b) Most globular proteins are denatured and lose their activity when briefly heated to 65 8C. However, globular proteins that c
frez [133]

Answer:

Explanation:

The higher temperature is the factor which is responsible for the process of denaturation of proteins in which the breaking down of hydrogen, disulphide bonds and destabilization occurs. This process breaks up the bond between the polypeptides.

The bovine pancreatic trypsin inhibitor comprises of 58 amino acids this consists of the disulphide bonds which are destroyed on heating as a result of this the inhibitor becomes inactive. But on cooling it comes to the original form as the internal structure starts making hydrogen and disulphide bonds again. Thus the activity of the BPTI again gets restored.
