AQA A LEVEL BIOLOGY PAPER 1 2021. Describe the induced-fit model based on enzyme action and how an enzyme acts as a catalyst. [3 marks] . 2 Scientists investigated the action based on the enzyme ATP synthase. They made reaction mixtures each containing: • ATP synthase • buffer (to control pH) • substrates. One based on the substrates required within these reaction mixtures is inorganic phosphate (Pi). Tick ( ) one box to show which other substrate the scientists must add to the ...

MetabolismAnabolism+catabolism. the chemical processes that occur within a living organism in order to maintain life. Enzymatic Reactions inside a living organism CarbonCarbon is an element with the atomic number 6, meaning it has four electrons in its outer shell. These electrons can form covalent bonds with carbon atoms or atoms of other elements. This allows a diversity of stable compounds to exist. LipidsA diverse group of Carbon containing macromolecules made up of carbon, hydroge...

This document is a full IA that achieved a grade 7 in IB biology. It offers a good structure for all lab experiments and can help in paper 3. It can also help in the igcse papers.

The information contains both the old syllabus and the new 2025 ib biology syllabus. The black notes are class notes, while the red not...

IB Biology SL — Topic 1 • Cell Biology with Complete Solutions Cell theory 1. All living things are composed of cells 2. Cells are the smallest unit of life 3. Cells only arise from pre-existing cells Striated muscle cell Exception to cell theory! → Muscle cells fuse to form fibres that may be very long (>300mm) → Consequently, they have multiple nuclei despite being surrounded by a single, continuous plasma membrane → Challenges the idea that cells always funct...
