Answer:
The answer to your question is: letter C
Explanation:
From the graph, we can conclude that catalase has a low activity at low temperatures. Activity increases a little at 30°C and this process is the highest at 40°C, after this temperature, activity disminishes again.
Options:
A. This option is wrong because the number of bubbles at this temperatures is low, maybe the enzyme is already denatured.
B. This answer is wrong, at 30°C the enzyme shows a low activity.
C. This answer is correct because at this temperature the enzyme produces the higher amount of bubbles.
D. The activity of the enzyme at 0°C was not tested.
Answer: The Parathyroid gland
Explanation:
The Parathyroid gland secretes "Parathormone", an hormone that exerts
- direct influence on the bone by INCREASING the release of bone calcium ion (Ca2+) into the blood
- affects the kidney by stimulating the renal tubules to eliminate EXCESS calcium in the urine.
Thus, the calcium balance of the body depends on the secretion of the Parathyroid gland
The answer is....... (drumroll)........ lipids!
