Which of the following would not be made in a ribosome? O enzymes
O cholesterol
O antibodies
O water-soluble hormones

cholesterol(lipid)

Explanation:

Ribosomes are called PROTEIN FACTORY

Ribosomes are involved in protein synthesis

Any metabolite or substance protein in nature can be synthesized on ribosomes

Since they are protein in nature hence can be synthesized on ribosome.

WRONG OPTIONS:

CHOLESTEROL IS LIPID IN NATURE

LIPIDS ARE NOT proteins and cannot be SYNTHESIZED ON RIBOSOME

LIVER DOES THIS FUNTION OF CHLESTEROL SYNTHESIS.

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.
