Biochemistry: SSC CGL Biology

Biochemistry has 11 questions in the SSC CGL Tier I bank: five from the 2023 shifts, four from the 2024 shifts and two from the 2025 shifts. They ask another name for a carbohydrate, where a sugar or pigment is found, and which amino acids the body cannot make. One page gives the two tables to learn.

The handout has every subtopic, worked example, formula and trap with answers shown. The formula sheet is the chapter’s formulas and traps alone, on one page.
