Answers

Photosynthesis:
Light-dependent reactions
Photosystems II then I
Occurs in thylakoidal membrane with light harvesting pigments including chlorophyll
Produces oxygen gas with splitting of water molecules
ATP and NADPH are produced with concentration gradient of lumen and stroma
Calvin Cycle
Occurs in stroma where CO2 is combined with RuBp (If aliens invaded, one thing they would take home is rubisco!!!)
Through process, G3P is formed which can be synthesized to make sugar

Cellular Respiration
Glycolysis-Citric/Krebs-Electron Transport Chain (ETC)
Glycolysis is anaerobic and produces 2 ATP and pyruvic acid/ pyruvate in the cytosol
The pyruvates are transported to mitochondria and enters the citric acid cycle; CO2 is produced and acetyl CoA is produced.
The NADP and FADH2 produced in the previous process are fed into ETC which, through chemiosmosis- protein ATP synthase, produces usable ATP for cell.
Through statistics, it is a maximum of 32 ATP produced through cell respiration, but transport of molecules, etc. reduces the number.

Answer from: Quest

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
