Study Notes
Atomic Structure and Chemical Reactions
- Atoms are composed of subatomic particles (protons, neutrons, electrons).
- Electrons play a role in chemical reactions.
- Valence electrons are crucial in chemical bonding.
- Water is a polar molecule.
Cell Structure and Function
- The cell is the fundamental unit of life.
- Cells have compartments like organelles.
- Ribosomes, Golgi apparatus, and mitochondria are important cell organelles.
- DNA is located within the cell.
Cellular Respiration
- Cellular respiration is how cells obtain energy.
- Glycolysis is a metabolic pathway that converts glucose into pyruvate.
- Glycolysis does not require oxygen.
- Pyruvate is converted to a 3-carbon molecule.
- Citric acid cycle further breaks down pyruvate.
- Electron transport chain is where most ATP is produced.
- Cellular respiration needs oxygen.
DNA and RNA
- DNA is a double-stranded molecule.
- Base pairing in DNA (A-T, C-G) differs from RNA (A-U, C-G).
- DNA is transcribed into RNA for protein synthesis.
- Transcription and translation occur in cells.
- DNA is replicated before cell division.
- mRNA is made in the nucleus, but translation occurs in the cytoplasm.
Cell Cycle and Mitosis
- Mitosis is for cell division.
- Meiosis is important for gamete production.
- DNA replicates before mitosis.
- In DNA, the bases (A, T, C, G) make up the middle part.
- In the DNA helix, Adenine pairs with Thymine and Cytosine pairs with Guanine.
Other Concepts
- Chromosomes are made of DNA wrapped around proteins.
- Genes are segments of DNA that code for proteins.
- Humans have autosomes and sex chromosomes.
