Terms in this deck (30)
1
Site of photosynthesis in a cell
Chloroplasts, which contain chlorophyll.
2
Site of aerobic respiration in a cell
Mitochondria.
3
Word equation for aerobic respiration
Glucose + oxygen gives carbon dioxide + water + energy.
4
Enzyme that digests starch in the mouth
Salivary amylase.
5
Function of bile
Emulsifies fats, giving lipase a larger surface to act on.
6
Deficiency disease: vitamin C
Scurvy.
7
Deficiency disease: vitamin D
Rickets.
8
Deficiency disease: protein
Kwashiorkor.
9
Blood vessel carrying oxygenated blood to the body
The aorta.
10
Test for starch
Add iodine solution: it turns blue-black.
11
Test for reducing sugar
Heat with Benedict's solution: a brick-red precipitate forms.
12
Test for carbon dioxide
It turns limewater milky.
13
Number of protons plus neutrons
The mass number of an atom.
14
Group 1 metals
The alkali metals: lithium, sodium, potassium. They get more reactive down the group.
15
Group 17 elements
The halogens: fluorine, chlorine, bromine, iodine. They get less reactive down the group.
16
Molar volume of a gas at room temperature and pressure
24 dm3 per mole.
17
Moles
Mass in grams divided by molar mass.
18
Acid + metal gives
A salt and hydrogen.
19
Acid + carbonate gives
A salt, water and carbon dioxide.
20
Anode in electrolysis
The positive electrode, where oxidation takes place.
21
Newton's second law
Force = mass x acceleration.
22
Formula for kinetic energy
1/2 x m x v^2.
23
Formula for power
Work done divided by time taken.
24
Ohm's law
V = IR.
25
Total resistance of resistors in series
R = R1 + R2 + R3.
26
Total resistance of resistors in parallel
1/R = 1/R1 + 1/R2 + 1/R3.
27
Wave equation
Speed = frequency x wavelength.
28
Most penetrating type of radiation
Gamma rays.
29
Half-life
The time taken for half of the radioactive nuclei in a sample to decay.
30
Refractive index
Speed of light in air divided by the speed of light in the medium.
