HL Paper 2
Proteins are an important group of chemicals found in all living organisms.
Draw a molecular diagram to show the formation of a peptide bond.
Outline how proteins are digested and the products of protein digestion absorbed in humans.
Explain how polypeptides are produced by the process of translation.
Describe how plants transport organic compounds from where they are made to where they are stored.
The processes of photosynthesis and respiration have some factors in common and others differ. Compare and contrast both processes for specific factors.
Humans rely on carbohydrates for much of their energy. Outline the process of digestion and absorption of starch in the human digestive system.
