the enzyme beta - galactosidase works best at 37°c. under optimal conditions, the enzyme beta - galactosidase looks like this:
which of the following images best represents what beta - galactosidase looks like at 4°c
image b
image c
image a

Explanation:

For Question 11, in many chemical and biological reactions, the production of carbon - dioxide gas, oxygen gas can cause bubble formation. Water is a liquid and hydrogen - peroxide is usually a liquid too and their production alone doesn't typically cause bubbles in the same sense as gas production. For Question 12, enzymes are proteins and at lower temperatures (4°C compared to 37°C optimal), their structure may start to change but not completely denature. Image c likely represents a completely denatured enzyme, image b is too similar to the optimal - condition structure, and image a shows a slight change in structure which is more likely at a sub - optimal lower temperature.

Answer:

Question 11: The production of carbon dioxide, The production of oxygen
Question 12: image a
