Answer: Enzymes reduce the activation energy associated with food molecules
Explanation:
Chemical entities such as yams, potatoes, eggs, etc., consist of elements linked together by chemical bonds like hydrogen bonds and covalent bonds.
To facilitate digestion, these bonds must be disrupted in order to convert carbohydrates into glucose and proteins into amino acids.
Therefore, when enzymes are introduced, they lower the bond strengths or activation energies by positioning them appropriately in their active sites, designed to cleave specific bonds.
As a result, digestive processes become faster in the presence of enzymes compared to without them.
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.

To establish the type of flask based on the molarity or concentration of the solutions, one should set up an experiment using dialysis tubes filled with distilled water, securing both ends of the tubes tightly. The mass of each tube should be noted, and labels should be affixed to the cups holding the solutions. After allowing the solutions to sit for 8 to 10 hours, weigh the tubes again. Due to diffusion, the tubes should experience weight loss as water exits them when immersed in the solutions.
