yup 25 marks per question.
25 marks from 3 points means 3 paragraphs.
in proteins in living systems talk about humans and animals..but most imp enzymes (digestive, reproductive etc) and so amino acids for things like skin...
glucose and glucose polymers are like amylose and amylopectin and other polysaccharides so talk about their structure...compact...easily hydrolysed etc..and how they r stored in muscles...
ions in biological processes...plants as well as humans? talk about diff minerals and imp ions like calcium
