Glycogen and Other Sugars Feed Glycolysis

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Stored glycogen and dietary sugars other than glucose, like fructose and galactose, convert into glycolysis intermediates and enter that same pathway.

Show

When blood glucose drops, liver and muscle cells break glycogen down into a glucose derivative feeding directly into glycolysis.

Watch for

These sugars join glycolysis partway through, at the point their structure matches an existing intermediate.
