Large numbers of ribosomes are present in cells that specialize in producing which of the following molecules?
a) lipidsb) glycogenc) proteinsd) cellulosee) nucleic acids

The correct answer is: C) proteins

Ribosomes are organelles involved in protein synthesis during translation which are composed of two subunits, the big and the small one , ribosomal RNA (rRNA) molecules and ribosomal proteins. Ribosome has binding sites for RNA binding: mRNA which contains codons for protein synthesis and tRNA which contains anticodons complementary to codons.

"d.) carbon dioxide and hydrogen sulfide"

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
