Study Notes

Photosynthesis

  • Water donates an electron during the process.
  • Carbon dioxide is essential for producing PGAL (3-phosphoglyceraldehyde).
  • Utilizes the Calvin cycle for carbon fixation.
  • Glucose is a primary product of photosynthesis.
  • Oxygen is released as a byproduct.
  • RuBP (Ribulose bisphosphate) is involved in the carbon fixation process.
  • NADPH acts as a reducing agent in the biosynthetic reactions.
  • Thylakoids are membrane-bound structures where the light-dependent reactions occur.
  • Requires pigments such as chlorophyll to capture light energy.
  • Chloroplasts are the organelles where photosynthesis takes place.
  • Photosystem I (PSI) and Photosystem II (PSII) play key roles in the light-dependent reactions.

Both Photosynthesis and Cellular Respiration

  • Both processes require a hydrogen carrier to facilitate energy transfer.
  • ATP is generated during both processes through oxidative phosphorylation and photophosphorylation.
  • Occur in plant cells, highlighting the role of plants in energy conversion.
  • Require enzymes to catalyze various biochemical reactions.
  • Utilize ATP synthase for synthesizing ATP from ADP and inorganic phosphate.
  • Metabolic pathways that contribute to cellular energy balance.
  • Make use of an Electron Transport System to transfer electrons and create a proton gradient.

Cellular Respiration

  • NADH serves as a crucial electron carrier in cellular respiration.
  • The matrix of the mitochondria is where many reactions of the Krebs cycle take place.
  • Cristae are the inner mitochondrial membranes that increase surface area for metabolic reactions.
  • Mitochondria are the organelles where cellular respiration occurs.
  • FADH2 also acts as an electron carrier and contributes to the energy yield.
  • Primarily occurs in heterotrophic cells that derive energy from organic sources.
  • Utilizes the Krebs cycle for breaking down glucose and producing ATP.
  • Mainly takes place in animal cells alongside other eukaryotic organisms.
  • Oxygen acts as the final electron acceptor in the electron transport chain.

Neither Photosynthesis nor Cellular Respiration

  • Synthesis of proteins is not part of either photosynthesis or cellular respiration processes.
  • NAG (N-acetylglucosamine) is not a hydrogen carrier used in these pathways.
  • No events part of photosynthesis or cellular respiration occur within the nucleus.
