PH Genes Temperature

Use the image to answer the question: Based on the graph, what is the optimal temperature for this enzyme?

• 15^oC

• 40^oC

• 30^oC

• 35^oC

Which of the following conclusions can be drawn from this graph?

• The optimum pH of the enzyme is 6.6.
  
• The optimum pH of the enzyme is 5.8
  
• The enzyme’s activity increases as pH increases 5.0 to 9.0
  
• The enzyme’s activity is greater around pH of 8.0 .
  

What happens when enzymes are heated to a high temperature?

• The enzymes die.

• The shapes of the enzyme are altered and it denatures

• The enzymes' amino acid sequence changes.

• The enzymes remain the same

Which enzyme is most efficient in a basic solution?

• A
• B

Which of the following denatures an enzyme?

• High Temperatures

• Incorrect pH

• Both

What 3 things impact enzyme function? Select all that apply.

• pH

• temperature

• substrate concentration

• water availability

• sun exposure

An enzymes optimal means its the environmental where the enzyme works....

• best

• worst

The _____ is when the enzyme function remains constant & is working at max activity due to all active sites being filled as soon as they release product

• optimal range

• point of saturation

• induced fit

• enzyme substrate complex

Some bacteria live in hot springs. Their enzymes function best at temperatures of 70 °C. How would these enzymes react at temperatures below 70 °C?

• The enzymes will be destroyed by lysosomes

• The enzymes will lose their bond structure and fall apart.

• The enzymes will need more energy

• The enzymes will function more slowly

Why is it important to maintain homeostasis?

• Enzymes function best at a specific temperatures and pH.

• It would take too much energy for reactions if it isn't balanced

• The body would be disorganized and enzymes would work too slowly

• There is no reason
