What is absorption?
Taking molecules into thebody
1 of 20
What is assimilation
Incorporating absorbed molecules into body tissue
2 of 20
What is the structure of glucose?
.
3 of 20
What is maltose broken down into?
Glucose + Glucose
4 of 20
What is sucrose broken down into?
Glucose + Fructose
5 of 20
What is lactose broken down into?
Glucose + Galactose
6 of 20
How is a bond broken down?
Hydrolysis reaction
7 of 20
How is a bond formed?
Condensation reaction
8 of 20
Lactose (lactose intolerance)
digested in SI --> epithelial lining produces lactase. Low lactase= high lactose= broken down by microorganisms= gas=bloated
9 of 20
Test for Reducing Sugar
Add Benedicts, heat= red
10 of 20
Test for Non-Reducing Sugar
Do Reducing test. If not red then add HCL to break down. Add sodium hydrocarbonate to neutralise. Do Reducing test again.
11 of 20
Test for proteins
Add sample, add sodium hydroxide, add dilute copper sulfate= purple
12 of 20
Test for Iodine
Add sample, add iodine=turns blue/black
13 of 20
Test for lipids
Add sample, add ethanol, shake, pour into water. lipid= cloudy
14 of 20
Structure of a protein
.
15 of 20
What bonds are between protiens?
Peptide bonds
16 of 20
Lock and key model
Enzyme substrate complex, substrate specific
17 of 20
Induced fit
Enzyme changes shape to fit around the substrate.
18 of 20
Non competitive inhibitor
Binds to allosteric site (not active site), causes bonds to break in active site= changes shape= innactive
19 of 20
Competitive inhibitor
Binds to active site so substrates can't bind
