A water-soluble hormone binds to its receptor on the plasma membrane. Arrange the events that follow in correct sequence. (1) alpha subunit-GTP complex alters cell activity (2) GTP binds to the alpha subunit replacing GDP (3) G-protein subunits separate from the receptor (4) alpha subunit separates from other two subunits (5) G-protein subunits bind to the receptor

Answer :

Answer:

G-protein subunits bind to the receptor

GTP binds to the alpha subunit replacing GDP

G-protein subunits separate from the receptor

alpha subunit separates from other two subunitsalpha subunit-GTP complex alters cell activity

Explanation:

5 2 3 4 1

Hormones are the chemical messengers that are signalling molecules and are transported or released in organs for behaviour and physiological changes.

The events in the correct sequence are:

(5) G-protein subunits bind to the receptor

(2) GTP binds to the alpha subunit replacing GDP

(3) G-protein subunits separate from the receptor

(4) Alpha subunit separates from other two subunits

(1) Alpha subunit-GTP complex alters cell activity

The events can be explained as:

  • The cell membrane contains receptors for signal transductions for response to extracellular actions.

  • The receptors present on the plasma layer are transmembrane proteins and are embedded in the plasma layer.

  • Cell receptors bind to molecules for initiating a physiological response.

Thus, the order of events is 5, 2, 3, 4 and 1.
