Answer 1

1. pentose phosphate pathway

The pentose phosphate pathway  is a metabolic pathway parallel to glycolysis. It generates NADPH and pentoses (5-carbon sugars) as well as ribose 5-phosphate, the last one a precursor for the synthesis of nucleotides. While it does involve oxidation of glucose, its primary role is anabolic rather than catabolic. The pathway is especially important in red blood cells (erythrocytes).

2. usually circular

Most bacteria have a genome that consists of a single DNA molecule (i.e., one chromosome) that is several million base pairs in size and is "circular". In addition, bacteria may have one or more smaller circular DNA molecules, called plasmids, that contain (usually) non-essential genes.

3.  the number of microbial cells.

Microbial growth refers to an increase in cell number, not in cell size.
