The main function of sugars in living organisms is to supply energy.
Answer:
It is essential for living organisms to maintain a non-equilibrium state in the concentrations of oxygen and carbon dioxide to facilitate gas exchange. If equilibrium is reached, both respiration and photosynthesis would cease.
Explanation:
- Gases flow from areas of higher concentration to lower concentration along their gradients.
- If organisms achieve equilibrium in carbon dioxide and oxygen levels, gas exchange into and out of cells would stop.
- Equilibrium signifies that gas concentrations equalize on both sides, halting any movement.
- Should gas exchange come to a standstill, respiration and photosynthesis in plants, as well as respiration in animals, would completely halt.

Response:
It would need a lower amount of bicarbonate to neutralize the acid.
Explanation:
Sodium bicarbonate (NaHCO3) is a partially soluble sodium salt that breaks down in water to create a weakly basic buffer solution. It separates in water releasing bicarbonate ions (HCO−), sodium ions (Na+), and H+.
2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g)
Buffer solutions are maintained in equilibrium. In a solution with a strong acid, the conjugate base reacts, while other carbonate ions release to form carbonic acid, driving the solution back toward balance.
HA ⇄ H+ + A-
Due to its buffering capability, which is how effectively it stabilizes the equilibrium, less bicarbonate will be required later on to neutralize the acid.
