The first conformer cis-isomer (Picture 1) has both substituents in equatorial positions. Other conformer (on the right) has both substituents in axial positions. The conformer with both substituents in equatorial positions is more stable.
Trans isomers have one substituent in an equatorial position and the other in an axial position (Picture 2). The conformer with the tert-butyl group in the equatorial position is more stable because tert-butyl group is larger.
Energy is released from ATP by the breaking of the phosphate bond. A<span>denosine triphosphate, or ATP, consists of a sugar called ribose, the molecule adenine and three phosphate groups. During the hydrolysis of ATP, the last phosphate group is transferred to another molecule, thus breaking the phosphate bond. This reaction causes energy to be released to power other activities within the cell.</span>
