Essential Concepts for EOCT: Mitosis, Meiosis, Enzymes, and Cellular Biology

Discover the top ten critical concepts you must know for the EOCT examination. From the basics of cell division, where mitosis produces two identical diploid cells and meiosis yields four genetically diverse haploid cells, to the crucial role of enzymes as catalysts in biological reactions, this guide covers it all. Understand passive transport mechanisms like diffusion and osmosis, the significance of DNA in evolution, cellular environments, and the energy production in mitochondria. Get equipped to excel in your biology assessments!

Presentation Transcript

  1. Top Ten Things I must know for the EOCT

  2. Mitosis Makes 2 Genetically identical diploid (2n) cells #10-Meiosis makes 4 genetically different haploid (n) cells

  3. Enzymes #9 • work to lower the activation energy; • fit like a lock and key; • work on a substrate, • can be denatured by heat. • They are PROTEINS • They don’t get used up • They are catalysts-they speed up a reaction

  4. #8Diffusion, osmosis, and facilitated diffusion are passive transport and do NOT require energy.

  5. #7The best evidence of evolution and relationships is found in DNA.

  6. #6Cells in a hypOtonic solution swell. • Cells in a hypertonic solution shrink.

  7. #5-DNA is in all living things and contains information for how to make PROTEINS. Amino acids to amino acid to amino acid…makes a protein.

  8. #4-Prokaryotes have NO nucleus. YOU are a Eukaryote-you have a nucleus and membrane bound organelles.

  9. #3The mitochondriais where energy is produced in the form of ATP during cellular respiration. The ETC (electron transport chain) makes the most ATP).

  10. #2The producers/autotrophs have the most energy-NOT the top consumers

  11. #1Energy Flows! • Matter recycles!
