What 2 environmental conditions can affect the activity of an enzyme quizlet?

What 2 environmental conditions can affect the activity of an enzyme?

Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.

What are 2 important abiotic factors that affect enzymatic activity?

Temperature, pH, enzyme and substrate concentrations, and the presence of activators and inhibitors are abiotic factors of enzyme activity. These factors either increase or decrease the rate of reaction. The optimal temperatures and pH that allow a faster rate for reactions to occur.

Which of the following environmental conditions does not affect the activity of enzymes *?

The correct answer: The factor which does NOT affect enzyme activity is d. Free Energy.

IMPORTANT:  Best answer: How does internal environmental scanning benefit the organization?

What environmental factors affect enzymes and metabolic rate?

Explanation: The temperature and pH of the environment, as well as the concentration of the substrate and enzyme, all affect the rate at which an enzyme catalyzes a reaction. As a result, enzymes have optimal conditions in which they can work at peak efficiency.

How the factors affect enzyme activity?

Several factors affect the rate at which enzymatic reactions proceed – temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

What factors affect enzyme activity quizlet?

Terms in this set (6)

  • Temperature. As temperature increases, the reaction rate increases, but if the temperature passes the optimal range, the enzyme will stop functioning.
  • pH. Each enzyme has a specific pH. …
  • Enzyme Concentration. …
  • Substrate Concentration. …
  • Presence of Inhibitors. …
  • Presence of Activators.

What are the optimum conditions for enzyme activity in the human activity?

The perfect conditions

Most enzymes in the human body work best at around 37°C – body temperature. At lower temperatures, they will still work but much more slowly. Similarly, enzymes can only function in a certain pH range (acidic/alkaline).

How can temperature affect enzyme activity?

As with many chemical reactions, the rate of an enzyme-catalysed reaction increases as the temperature increases. However, at high temperatures the rate decreases again because the enzyme becomes denatured and can no longer function. An optimum activity is reached at the enzyme’s optimum temperature. …

What are the factors that affect enzyme activity Class 11?

Enzyme activity is affected by factors such as temperature, pH, the concentration of substrates, presence of inhibitors, allosteric regulators, etc.

IMPORTANT:  Quick Answer: What are the similarities of ecosystem and environment?

Which of the following will not negatively affect the activity of an enzyme?

Enzyme concentration. … The option which does not affect the enzyme activity will be the answer.

What are the 4 factors that affect enzyme activity?

Several factors affect the rate at which enzymatic reactions proceed – temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

Which of the following does not affect the velocity of an enzyme catalyzed reaction?

Which of the following does not affect the velocity of an enzyme-catalyzed reaction? Explanation: The size of an enzyme is typically not indicative of the rate of the reaction that it catalyzes. All other parameters are taken into account when considering reaction velocity.

Are enzymes sensitive to environmental conditions?

Proteins (most enzymes are proteins) are sensitive to their environment. You have already seen how changing the substrate concentration and the temperature can affect the efficiency of an enzyme’s ability to catalyze a chemical reaction.

How do enzymes affect the environment?

Enzymes are proteins which are readily and ultimately biodegradable in the environment [1] [2]. Apart from aquatic toxicity resulting from of the catalytic effect (protein degradation) inherent to protease enzymes there is no environmental hazardous effect from enzymes in the environment.

What environmental conditions denature an enzyme?

Temperature: That’s a good one. Proteins change shape as temperatures change. Because so much of an enzyme’s activity is based on its shape, temperature changes can mess up the process and the enzyme won’t work. High enough temperatures will cause the enzyme to denature and have its structure start to break up.
