C. Deoxyribose sugar because the phospahte group, the nitrogen base, and ribose sugar is needed for ATP.
The change in shape of enzyme molecules that occur at high temperatures is know as sythesis
Unlike osmotic pressure, tonicity is influenced only by solutes that cannot cross the membrane, as only these exert an effective osmotic pressure. Solutes able to freely cross the membrane do not affect tonicity because they will always equilibrate with equal concentrations on both sides of the membrane without net solvent movement.
