The answer to the question above is letter "B. stroma". In the stroma are grana, stacks of thylakoid, others. Stroma contains important molecules which are useful for the photosynthesis and other metabolic functions of the cells. It may also contain enzymes and ions.
Answer:
the answer is D) DNA and RNA
1. The correct answer is pH.
The activity of the enzymes might be affected by environmental changes such as change in pH. Each enzyme has the point when it is the most active and this value is known as the optimum pH. Extremely high or low pH values can lead to loss of enzyme activity and stability.
Phosphofructokinase is sensitive to acidity, meaning that it is inhibited by low pH levels.
2. The correct answer is temperature.
Enzyme is sensitive to the environmental conditions such as temperature changes.
Temperature is a factor that usually increases the rate of enzyme-catalyzed reactions by increasing the activity of enzymes. But, after reaching the optimum temperature, reaction rate abruptly declines. This happens because enzymes are deactivated or denatured at a certain temperature (above 40° C).
Because Yuki started off with a bowl of ice right. She sat in the room and watched the ice melt, the ice melts when the temperature is to hot then she heats up the water on a burner and it vaporizes when the water gets to hot.
Answer: Option II. inhibited by adenylylation.
Option III. activated by uridylylation of the PII subunit of adenylyltransferase.
Explanation:
Glutamine syntherase is an enzyme that is found in the mitochondria. Glutamine syntherase acts as a catalyst in the reaction that produces glutamine from glutamate and ammonia.
