Answer is 12 billion kilometers
That is what quizlet says
B. Experiment 1, because it gave the same results every time
D. encloses specific structures
hope this helped:)
Explanation:
Menstruation is the cyclic changes taking place in women every month which involves the sloughing of the uterine walls.
The menstrual cycle involves the coordination of two-cycle: the ovarian cycle and the uterine cycle.
The menstrual cycle is controlled by the gonadotrophin hormones which are the Luteinizing hormone (LH) and the Follicular stimulating hormone (FSH) and ovarian hormones which are: progesterone and estradiol.
The level of these hormones during each phase are:
1. Follicular phase / proliferative phases- Estradiol level increases/ FSH level declines
2. Ovulation- LH hormone level at the peak, estrogen level at the peak
3. Luteal phase/ secretory phase- Progesterone and estrogen level elevates / LH and FSH level declines
If the active site of an enzyme is damaged, leaving it nonfunctional, the reaction proceeds as if it were a non-catalyzed reaction without a lowering of the activation energy.
<h3>What is the active site of an enzyme?</h3>
An active site of an enzyme is the site in an enzyme which the substrate molecules binds to in order for the enzyme to perform its function.
The effective binding of substrate to active site of an enzyme enables catalysis to occur.
Thus, when the active site of an enzyme is damaged, the enzyme becomes non-functional.
Based on the graph, the reaction proceeds as if it were a non-catalyzed reaction without a lowering of the activation energy as seen in the purple colored graph.
In conclusion, effective bonding of substrate to enzyme active site is essential for catalysis to occur.
