Name the carbohydrates found in plants
Starch. Cellulose
1 of 16
Name three carbohydrates that cintain glycosidic bonds
Starch. Cellulose. Glycogen
2 of 16
Carbohydrate that contains Beta glucose
Cellulose
3 of 16
A feature of starch that allows it act as a storage substance and explain why
Coiled, whats stored is tightly packed so more can be stored than if it wasnt coiled
4 of 16
Something you have to remember when doing a microscope scale question
all units of measre are the same
5 of 16
What happens when enzymes are heated too high
Temperaqture passes optimum ad hydrogen bonds are broken causing active site to change. the enzyme is now denatured. this means the substrate will no longer fit
6 of 16
What average do we mainly use?
Mean
7 of 16
Why can nucleotides only be added 5 prime to 3 prime
Free nucleotides are added by dna polymerase. Dna polymerase is specific as its only complementary to other bases and binds to 5prime. Bases only bind with their compleentary base pair. Shapes of the 5 primee end and 3 prime end are different.
8 of 16
Describe how you test for a lipid
Add alohol then water and iflipids are present a milky emulsion forms

how can you tell a fatty acid is unsaturated
double bond between carbon and hydrocarbon chain
11 of 16
Advantage of cholesterol in the red blood cell
stops oxygen from leaking out of the cell
12 of 16
Describe the countercurrent system
water and blood flow opposite. maintains the gradient. along the whole length of the gill
13 of 16
volume of water over gils increases as temperature does. why?
Increase enzyme activity. Less oxygen in the water
14 of 16
Two adaptations that cause rapid absorption
microvili and mitochondria
15 of 16
why cant antigens pass through cell surface membranes
not lipid solubles. too large. antigens not complementary
