Q.1 Protease is an enzyme in the human body that catalyzes a chemical reaction in which proteins are broken down into smaller molecules so that the body can use them. Which is a likely outcome if protease does not function properly?
1.The cells of the digestive system will increase in temperature and catalyze the reaction.
2.The chemical reaction will not occur, and the body will not be able to absorb the protein it needs.
3.The activation energy needed for the chemical reaction will be lowered.
4.The body will use a different enzyme to catalyze the chemical reaction.
Q.2 How does temperature affect enzyme activity in a chemical reaction?
1.The rate of a chemical reaction initially increases with decreasing temperature and then decreases, eventually stopping, when the temperature gets too low.
2.The rate of a chemical reaction initially increases with increasing temperature and then decreases, eventually stopping, when the temperature gets too high.
3.The rate of a chemical reaction always decreases with increasing temperature and always increases with decreasing temperature.
4.The rate of a chemical reaction initially increases with increasing temperature and continues to increase indefinitely as temperature continues to increase.
Warning, Anonymous is wrong on some of them.
Protease is an enzyme in the human body that catalyzes a chemical reaction in which proteins are broken down into smaller molecules so that the body can use them. Which is a likely outcome if protease does not function properly?
A.1: 2. The chemical reaction will not occur, and the body will not be able to absorb the protein it needs. So, if protease doesn't do its job, you'll have a hard time digesting those burgers and gaining those muscle gains!
A.2: 2. The rate of a chemical reaction initially increases with increasing temperature and then decreases, eventually stopping, when the temperature gets too high. So, just like how a conversation at a party can start off with a lot of energy, things can get a little too hot and overwhelming if the temperature keeps rising.
A.1 : The likely outcome if protease does not function properly is that the chemical reaction will not occur, and the body will not be able to absorb the protein it needs.
To arrive at this answer, we can use our knowledge of the function of protease in the body. Protease is responsible for breaking down proteins into smaller molecules so that the body can absorb and use them. If protease does not function properly, this breakdown process will not happen, and the proteins will remain in their larger form, making it difficult for the body to absorb them. This can lead to nutritional deficiencies and various health problems.
A.2 : The rate of a chemical reaction initially increases with increasing temperature and then decreases, eventually stopping, when the temperature gets too high.
To understand how temperature affects enzyme activity in a chemical reaction, we need to consider the concept of enzyme kinetics.
Enzymes are protein molecules that act as catalysts, meaning they speed up the rate of a chemical reaction without being consumed in the process. Enzyme activity is affected by temperature.
At low temperatures, enzymes have low activity because the reactant molecules have low energy, and the collisions between enzyme and substrate (the molecule the enzyme acts upon) are infrequent. As the temperature increases, the kinetic energy of the reactant molecules also increases, leading to more frequent and energetic collisions with the enzyme. This results in an increase in the rate of the chemical reaction.
However, at high temperatures, the enzyme's active site, where the substrate binds, can become denatured. Denaturation refers to a loss of the enzyme's shape and structure, rendering it ineffective. At this point, the rate of the chemical reaction begins to decrease and eventually stops.
Therefore, the correct answer is that the rate of a chemical reaction initially increases with increasing temperature and then decreases, eventually stopping, when the temperature gets too high.
