Energy chemical bonds
Webthe energy which is stored in the bonds of chemical compounds (molecules and atoms). It is released in the chemical reaction and mostly produces heat as a by-product, known as an exothermic reaction. E xamples of stored chemical energy are biomass, batteries, natural gas, petroleum, and coal. Mostly, when the chemical energy is released from a ... WebWeak hydrogen bonds between complementary strands are easily disrupted during DNA replication because they are not high-energy chemical bonds. TRUE/FALSE The antiparallel arrangement of double-stranded DNA is due to the phosphate group being bonded to the 3' carbon on one strand and the 5' carbon on the complementary strand.
