P450scc or cholesterol side chain cleavage enzyme is an enzyme that converts cholesterol into pregnenolone (the precursor for steroids). The kinds of steroid hormones are mineralocorticoids (i.e. aldosterone) glucocorticoids (i.e. cortisol), and sex steroids (i.e. testosterone, estrogen). In the event where P450scc is blocked, then there will be no production of mineralocorticoids, glucocorticoids, and sex steroids. There will be no production of aldosterone, cortisol, estradiol, testosterone, and progesterone. This disease is called Lipoid Congenital Adrenal Hyperplasia.
I think the answer is most likely A
Answer:
B) Help produce oxygen
C) Help make foods
D) Help break down dead materials
Explanation:
B - Life on Earth <em>depends</em> on protists since they are the ones who supply us with oxygen.
C - Provide food to other living organisms in food chains/webs.
D - Even, recycle important nutrients just for other life forms to use (some protists may also be decomposers; as they also release nutrients into the environment).
Prokaryotic cells are cells that have no nucleus, and are either cells of bacteria or protists. Eukaryotic cells are cells that do have a nucleus, and may have other organelles that prokaryotic cells don't have, like a vacuole or lysosome, etc. Hope this helps!
