# Glycogenolysis can be correctly represented by which of the following?

Question

glucose→glycogen

glycogen→glucose

pyruvate→glycogen

glyogen→pyruvate

Answer 1

glycogen→glucose

Glycogenolysis (also known as "Glycogenlysis") is the catabolism (breakdown) of glycogen by cleavage of a glucose monomer through cleavage with inorganic phosphate to produce glucose-1-phosphate. This derivative of glucose is then converted to glucose-6-phosphate, an intermediate in glycolysis.

Answer 2

Questions like these can be answered quite simply by BREAKING THE WORD DOWN

GLYCOGEN-O-LYSIS

GLYCOGEN - A branched polymer of GLUCOSE. The STORAGE POLYSACCHARIDE in most animals.

LYSIS - Literally means 'SPLITTING'

So this means "SPLITTING of GLYCOGEN". Since glycogen is made up of glucose,

Glycogen ---> Glucose is the correct equation (:

-----------------------------

To prove how easy this is, here is another example.

"GLUCONEOGENESIS"

can be split into

GLUCO-NEO-GENESIS

GLUCO - A shortened form of the word "GLUCOSE"

NEO - or "NEW"

GENESIS - "GENERATION" or "SYNTHESIS"

So this means "THE GENERATION OF NEW GLUCOSE"

This process actually involves proteins and fatty acids, so it could be expressed as

Proteins/Fatty acids ---> Glucose

Hope this helps (:
