Answer
This reaction is an example of an anabolic process rather than catabolic, as it involves the synthesis of maltose from glucose units.
Step 2

Answer
This is also not correct because fatty acids and glycerol are components of lipids; this indicates a breakdown and not the formation of an exergonic reaction.
Step 3
C. ATP and water from ADP and inorganic phosphate.

Answer
This is a misleading statement since the formation of ATP from ADP and inorganic phosphate is an endergonic reaction requiring energy, not an exergonic catabolic reaction.
Step 4
D. glucose and oxygen from carbon dioxide and water.

Answer
This reaction represents photosynthesis where glucose is produced from carbon dioxide and water, indicating energy absorption rather than a catabolic reaction.
