Which of the following statements about mitochondrial chemiosmosis is NOT true? A
A proton gradient is established across the inner membrane of the mitochondrion.
B
The potential energy released from the mitochondrial proton gradient is used to produce ATP.
с
The mitochondrial proton gradient provides energy for muscle contraction
D
Proteins embedded in the inner mitochondrial membrane play an important role in ATP synthesis,
E
Heat energy is required to establish the electron transport chain

Heat energy is required to establish the electron transport chain

Explanation:

The rest of the choices are true about mitochondrial chemiosmosis

Option C, Analogous Organ

Explanation:

Thorns and spines are analogous organs. Analogous organs are those which have different function but have similar look and structure.  

Thorns are basically modified stem and spines are modified leaves. Both the thorns and spines are different in structure but they have same function which are as follows -  

a)They control the rate of respiration

b)Provide protection to the plants
