Polysaccharides As Energy Stores Flashcards
What are polysaccharides?
Polymers made of monosaccharides
What is the respiration word equation?
Glucose + oxygen -> carbon dioxide + water
Joining together lots of glucose molecules creates what?
A store of energy
What are characteristics of glycogen?
1-4 and 1-6 carbon bonds.
Chain formation with branches
Less tendency to coil
Easier to remover monomer units as has more ends
What are the characteristics of amylose?
Coils into spiral shape
Bind on carbons one and four
Hydroxyl group on carbon two for hydrogen bonds
Why are polysaccharides good energy stores? (5)
Compact
Easily sipped off
Branched stores mean the can be shipped off simultaneously
Less soluble in water than monosaccharides
Why is it important that polysaccharides are less soluble in water?
If the dissolved it would disrupt the cells water potential
Why are polysaccharides less soluble?
Because of their size
They are larger than monosaccharides
Why would branches need to be snipped off at the same time?
When energy is required quickly
