Which statements regarding the atp-adp cycle are true 1.atp synthesis takes place in the mitochondria of eukaryotic cells 2. atp is regenerated from adp the process of phosphorylation 3. energy is stored in the covalent bonds between phosphates, with the greatest amount of energy in the bond between the second and third phosphate groups 4.most of the readily available energy stored in atp is stored during the manufacture of adenosine 5.the ribose sugar in the model above is the direct product of photosynthesis

Options 1, 2 and 3 are true.

in the eukaryotic cells ATP synthesis takes place in the mitochondria.

ADP + ip → ATP

Formation of ATP is called phosphorylation. synthesis of ATP occurs in presence of an enzyme ATP synthase. Energy is stored in the terminal covalent bond of ATP.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
