All the Biology essay titles throughout the years

Mistakes I have made in Bio essays before:

  • Complete the cycle in cycle essays

  • There is no GP in glycoslysis

  • The phagocyte moves down the concentration gradient of chemical released by plant

  • Insulin doesnt follow second messenger model, only glucagon and adrenaline!!

  • Must say homologous chromosomes align randomly at the equator => Independent segregation

  • Must say DNA helicase (but RNA polymerase is acceptable) for hydrogen bond breaking // RNA polymerase to join nucleotides together via condensation reaction to form phosphodiester backbone

2017:

  1. The importance of nitrogen containing substances in biological systems

  2. The importance of diffusion in organisms

2018:

  1. The importance of the control of movement in cells and organisms

  2. The importance of interactions between cells and between organisms

2019:

  1. The importance of DNA as an information carrying molecule and its use in gene technologies

  2. The importance of bonds and bonding in organism

2020:

  1. The functions of enzymes and their importance in organisms

  2. The causes and importance of variation and diversity in organisms

2021:

  1. The importance of complementary shapes of molecules in organisms

  2. The importance of ions in metabolic processes

2022:

  1. The uses and importance of ATP in organisms

  2. The importance of cycles in biology

  • For this question, make sure to complete the whole cycle, to get the mark !!

2023:

  1. The importance of interactions between organisms and their environment

  2. The importance of membranes in the functioning cells

2024:

  1. Phosphorus-containing substances and their importance in biological systems
