Question

QUESTION 6 Which of the following is/are likely to elicit a rapid, reversible response? O An odorant that binds to a G protein-coupled receptor O A growth factor that binds to a receptor tyrosine kinase o Asteroid hormone O Both GPCR and growth factor signaling

Answer 1

6. Both GPCR and growth factor signalling are reversible response.

7. First Option is correct. It will have an extremely high activation energy.

Activation energy is the minimum amount of ​​​​energy that is required to transform a molecule to another.

8. >1: <0

Increase in the concentration of reactants will generally increase the reaction rate, because more of the reacting molecules are present to form the products. So the reaction will be spontaneous, so ∆G will be <0. For spontaneous process, under standard conditions, Keq will be >1.

9. Kinases.

10. The sign of 2 could be reversed.

Explanation -

This is an endergonic reaction in which ∆G>0.

The process of conversion of ATP to ADP is an Exergonic process, where the energy is released.

i.e., ∆G <0.

So to achieve this, we need to change the sign of 2.

Then the graph will be as follows :
