Hi there,

My teacher attended a pixl conference and a representative from AQA gave the following information. Apparently every 2 or 3 years everything in the spec has to be covered so this is stuff that has not been covered and may come up.

Parts of B2 spec not covered in 2016 or 2015 exam – Possibly more likely to be in the 2017 exam (from AQA rep. at PiXL conference)
  • Structure of yeast and bacterial cell
  • Dissolved substances (definition, and factors affecting, movement of oxygen)
  • Large multicellular organisms develop systems for exchanging materials; during development of multicellular organisms, cells differentiate so that they can perform different functions.
  • Plant organs including stems, roots and leaves – label and describe their functions.
  • Plant tissues – epidermal, mesophyll, xylem and phloem – identify and describe their function.
  • Glucose made in photosynthesis can be converted into insoluble starch for storage and it can be used in respiration.
  • To produce proteins, plants also use nitrate ions that are absorbed from the soil.
  • The shape of an enzyme is vital for its function. High temperatures change the shape.
  • Amylase is produced in the salivary glands, pancreas and small intestine. It catalyses the breakdown of starch into sugars in the stomach and small intestine.
  • Microorganisms produce enzymes that pass out of cells. These have many uses in the home and industry.
  • Aerobic respiration takes place continuously in animals and plants.
  • Word equation for aerobic respiration.
  • Muscles store glucose as glycogen which can then be converted back to glucose for use during exercise.
  • Mitosis occurs during growth or to produce replacement cells.
  • The type of cell division in which a cell divides to form gametes is called meiosis.
  • Most types of animal cell differentiate at an early stage where as plant cells retain the ability to differentiate throughout life. In mature animals…
  • Chromosomes are made up of large molecules of DNA which has a double helix structure.
  • Gene – section of DNA – codes for a particular combinstion of amino acids – makes a specific protein.
  • In human body cells, one of the 23 pairs…
  • Each person apart from identical twins has unique DNA. This can be used in DNA finger printing.
  • Cystic fibrosis…
  • Embryo screening…

Our teacher only gave us B2 predictions, sorry !

However as soon as I get hold of the C2 and P2 predictions I will post them
