Indicate whether each of the following reactions is anabolic or catabolic by circling the appropriate word: reaction type of reaction 1. glucose + glucose → glycogen

The reaction of Glucose + Glucose → Glycogen is called glycogenesis and is an anabolic reaction.

Explanation:  

Metabolic reactions can be anabolic or catabolic. Anabolic reactions are those where small molecules are joined to form a larger molecule; and the use energy. On the other hand, catabolic reactions are those where large molecules are broken in smaller molecules; and they release energy.  

Glucose molecules are smaller than Glycogen. For this reason, the metabolic reaction of Glucose + Glucose → Glycogen is an anabolic reaction called glycogenesis.

glycogenesis  

Two types of metabolic reactions take place in the cell: 'building up' (anabolism) and 'breaking down' (catabolism).

Anabolic reactions use up energy. They are endergonic. In an anabolic reaction small molecules join to make larger ones. For example, the following condensation reactions that occur in cells are anabolic:
