This 25-slide powerpoint presentation covers 'Topic 2.4 - Proteins' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note. The topic has been divided into 3 sections:
A - Amino Acid
B - Protein Structure
C - Protein Function
The presentation itself contains minimal information as it is intended
to be used with teacher guidance. They are also formatted to be visually pleasing and to print well for handouts or revision. Please see the preview file for an idea of the slide aesthetic and level of detail.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
U1: Amino acids are linked together by condensation to form polypeptides.
U2: There are 20 different amino acids in polypeptides synthesized on ribosomes.
U3: Amino acids can be linked together in any sequence giving a huge range of possible polypeptides.
U4: The amino acid sequence of polypeptides is coded for by genes.
U5: A protein may consist of a single polypeptide or more than one polypeptide linked together.
U6: The amino acid sequence determines the three-dimensional conformation of a protein.
U7: Living organisms synthesize many different proteins with a wide range of functions.
U8: Every individual has a unique proteome.
A1: Rubisco, insulin, immunoglobulins, rhodopsin, collagen and
spider silk as examples of the range of protein functions.
A2: Denaturation of proteins by heat or by deviation of pH from the
A3: Drawing molecular diagrams to show the formation of a peptide bond.
