Scientists compare a specific type of enzyme from two species. One species is a bacterium. Many enzymes are found in the cytoplasm of human body cells. These enzymes would be expected to function optimally at which of the following temperatures and pH values? *
What are your choices?
Enzymes found in the cytoplasm of human body cells are generally adapted to function optimally at temperatures around 37 degrees Celsius and at a pH value of around 7. This is because the human body maintains a relatively constant internal body temperature and pH level.
To determine the optimal temperature and pH values at which enzymes found in the cytoplasm of human body cells would function optimally, we need to understand some basic concepts.
Enzymes are proteins that catalyze biochemical reactions in living organisms. They have specific temperature and pH requirements for optimal activity. The temperature affects the rate of enzyme-catalyzed reactions, while pH affects the enzyme's structure and charge.
In general, enzymes found in the cytoplasm of human body cells work optimally at a temperature of around 37°C (body temperature). This is because they are adapted to function within the human body, which has a stable temperature.
Regarding pH, enzymes found in the cytoplasm of human body cells typically function optimally at a neutral pH of around 7. This is because our body's internal environment, such as the blood and cytoplasm, is maintained at a pH close to neutral.
Now, let's apply this knowledge to the given scenario where scientists are comparing a specific type of enzyme from two species: a bacterium and human body cells. Since the question specifically asks about enzymes found in the cytoplasm of human body cells, we should focus on the optimal conditions for those enzymes.
Therefore, the expected temperature for the enzymes found in the cytoplasm of human body cells would be around 37°C, and the expected pH value would be around 7 (neutral).
To summarize:
- Enzymes in the cytoplasm of human body cells function optimally at a temperature of around 37°C.
- Enzymes in the cytoplasm of human body cells function optimally at a pH value of around 7 (neutral).
