Cells synthesise different molecular chains using distinct monomers, as shown in the two examples below - VCE - SSCE Biology - Question 1 - 2021 - Paper 1

This is the correct answer. The formation of bonds X and Y through the synthesis of polymers typically involves condensation polymerisation, where monomers join together and release water as a byproduct.

This statement is misleading. While the breaking of bonds can release energy, the formation of new bonds such as X and Y does not necessarily imply that energy is released for immediate use in the cell.

This statement is inaccurate as the formation of chemical bonds X and Y is not specifically part of the Calvin cycle, which is primarily involved in carbon fixation and carbohydrate synthesis.
