Answer:
Explanation:
Although protons resemble other positive ions such as Na+ and K+ in their movement across membranes, in some respects they are unique. Hydrogen atoms are by far the most abundant type of atom in living organisms; they are plentiful not only in all carbon-containing biological molecules, but also in the water molecules that surround them. The protons in water are highly mobile, flickering through the hydrogen-bonded network of water molecules by rapidly dissociating from one water molecule to associate with its neighbor, Protons are thought to move across a protein pump embedded in a lipid bilayer in a similar way: they transfer from one amino acid side chain to another, following a special channel through the protein.

This question is incomplete. However, let's understand some terms
Activation energy is the minimum amount of energy required for a reaction to proceed. Under normal condition, when the activation energy is high, it takes longer for the reaction to proceed than when it is low.
The burning of marshmallow is an exothermic reaction as it involves the transfer of heat energy into the environment.
They play an important role in the control system by sensing defects that occur during essential processes such as DNA replication or chromosome segregation, and inducing a cell cycle arrest in response until the defects are repaired.
D: Where two continental plates are colliding, creating a convergent boundary. One plate slips under the other because of convection currents in the mantle.
