Light Dependent Stage/ photochemical reaction/ light reactions: Word Equation: Water ( Hydrogen ions + Oxygen ((: light + chlorophyll) Site: On the Thylakoid membrane of the chloroplast Major events: • Light absorption o Chlorophyll in the thylakoids absorbs light. The energy absorbed is used for photolysis (splitting of water molecules). • Photolysis of water (Photodissociation) o The

Photosynthesis is the process of transforming light energy into chemical energy that is used to build carbohydrates. Light reactions occur in the thylakoid membrane of the chloroplast‚ sunlight and water are the substrates for this reaction. The conversion of light energy can go through two pathways: noncyclic and cyclic. In noncyclic light transport‚ both Photosystems II and I are involved producing ATP and NADPH. Photosystem II absorbs 680 nm of light energy‚ with the oxidation of water; chlorophyll

eukaryotes because they don’t need the space as they don’t have any organelles. If they were any bigger‚ it would be useless. Eukaryotes however are larger because they have so many organelles e.g. Golgi bodies‚ endoplasmic reticulum‚ nucleus‚ chloroplasts etc. Prokaryotes tend to be 0.2-2.0 in diameter while the eukaryotes tend to be 10-100 m in

differences is that Prokaryotic cells are much smaller than Eukaryotic cells. This is probably the most obvious difference. Eukaryotic cells are much larger and contain things that look like smaller cells inside of them. (Mitochondria and little chloroplast‚ which are necessary for survival in Eukaryotic cells.) The third major difference is that Prokaryotes have no organelles; Eukaryotes have organelles and are divided into many different functional components. Even though these cells have clear

BIO 101 Lecture Notes for Respiration‚ Fermentation‚ and Photosynthesis Respiration During aerobic respiration‚ glucose is completely oxidized (all H’s removed) leaving CO2 as an endproduct. The H’s are taken by coenzymes (NAD and FAD) to the electron transport chain. There the energy is drained from the hydrogen electrons and the energy is used to make ATP. The H’s are ultimately accepted by O2 to make H2O as an endproduct. Respiration occurs in three major stages: 1) Glycolysis

used‚ and from there you can tell how much water has been used. Photosynthesis is the process by which green plants‚ algae and some bacteria absorb light energy and use it to synthesize organic compounds. In green plants‚ photosynthesis occurs in chloroplasts‚ that contain the photosynthetic pigments. Photosynthesis occurs by slightly different processes in C3 and C4 plants. Factors which can affect this are the stomata. Plants can regulate the movements of water vapor‚ O2 and CO2 through the leaf surface
