Hint
Answer
Formula for aerobic respiration
6O2 + C6H12O6 = 6CO2 + 6H2O
Formula for anaerobic respiration
C6H12O6 = 2C3H6O3 + Energy
Word formula for aerobic respiration
Oxygen + Glucose = Carbon dioxide + Water
Word formula for anaerobic respiration
Glucose = Lactic acid + Energy
Formula for photosynthesis
6CO2 + 6H2O = C6H12O6 + 6O2

Eukaryotes
Contain DNA within nucleus
Prokaryotes
Have no nucleus to contain the DNA
Diffusion
The net movement of gases or dissolved solids from an area of high concentration to an area of low concentration down a concentration gradient until equilibrium is reached
Osmosis
The movement of water molecules from an area of high water potential to an area of lower water potential down the water potential gradient across a partially permeable membrane
Active Transport
The movement of substances from an area of low concentration to an area of high concentration against the concentration gradient using energy
Phagocytes
A type of immune cell that can surround and kill microorganisms, ingest foreign material and remove dead cells
Complement Activation
A cascading event like the falling of a row of dominoes
Lymphocytes
A type of white blood cell that determine the specificity of the immune response to infectious microorganisms
Neutralisation
The ability of antibodies to block the site(s) on bacteria or viruses that they use to enter their target cell
Phagocytosis
A cellular process for ingesting and eliminating particles
MRNA
Messenger RNA is a singles-stranded RNA molecules that is complementary to one of the DNA strands of a gene, it carries the genetic information needed to make proteins
mRSA
Methicillin-resistant Staphylococcus aureus is a strain of antibiotic-resistant bacteria
How to test for: Carbohydrates - Starch
Iodine solution turns blue-black in presence of starch
Carbohydrates - Reducing Sugars
Benedict's solution turns orange-red when heated in the presence of reducing sugar
Proteins
Biuret reagent turns mauve-purple when mixed with protein
Lipids
2cm^3 of ethanol is mixed, then an equal volume of water is added forming milky-white emulsion in the presence of lipids
