Answer:-

• With the HELP of a diagram show that how breakdown of glucose done through various pathways.... In the very first stage the Glucose which is a 6-carbon molecule is BREAKS into pyruvate which is a 3-carbon molecule in the cytoplasm. After that they are BROKEN down by three DIFFERENT pathways to RELEASE energy.

Different ways in which glucose breaks down:-

➜ The following are the various ways in which glucose is broken down.

❍Aerobic Respiration
