QuestionAnswer
Where does light dependent occur? What are the reactants and products? Occurs in the thylakoids. Reactants are light energy and water. Products are oxygen, ATP and NADPH
Where does light independent occur or Calvin cycle? What are the reactants and products? Occurs in the stroma. Reactants are ATP, NADPH, CO2, and RuBP
Location of the glycolysis process. State the reactants and products. Anaerobic or aerobic? Cytoplasm. Reactants are 2 ATP and glucose. Products are 2 ATP and 2 pyruvate. Anaerobic
Location of Krebs Cycle. Reactants and products. Anaerobic or aerobic? Mitochondria. Reactants are 2 pyruvate and oxygen. Products are 2 ATP, CO2, NADPH, and FADH. Aerobic
Location of ETC, reactants and products. Anaerobic or aerobic? Inner membrane of the mitochondria. Reactants are NADH and FADH. Products are 32 ATP and water. Aerobic
What is the metabolic pathway and what does it involve? It is a series of chemical reactions where the product of one reaction is the substrate for the next reaction, and involves coenzymes.
What is the difference between catabolic and anabolic pathways? Which one if for photosynthesis and cellular respiration? Catabolic releases energy by breaking down larger molecules. Anabolic uses the energy that is released to build larger molecules. Anabolic is for photosynthesis and catabolic is for cellular respiration.
How does ATP store energy and how does it release energy? ATP energy is stored in the phosphate bonds. Energy is released when the 2nd and 3rd phosphate bond is broken.
What is hydrolysis? When applied to a molecule of ATP, what does it result in? Hydrolysis is the chemical breakdown of a compound due to a reaction with water. It results in ADP.
What is oxidation? A material loses electrons by a transfer to another material.
Could Krebs Cycle occur without oxygen? why? No, because Krebs Cycle is aerobic, meaning it requires energy.
How many useable ATP molecules are produced during cellular respiration? How many are required to start glycolysis? There are 36 ATP molecules that are produced during cellular respiration. 2 ATP molecules are required to start glycolysis.
What two process are used to make ATP in a human when there is no oxygen? Lactic Acid Fermentation and Glycolysis
What are the two products of lactic acid fermentation? 2 lactic acid and 2 ATP
What are the products of alcohol fermentation? CO2, ethanol, and 2 ATP
How many ATP are produced with and without oxygen? List steps that each route requires. With oxygen 36 ATP: starts with glycolysis, 2 ATP, then Krebs Cycle Without oxygen 4 ATP: starts with glycolysis, 2 ATP are produced
Describe the structure if a chloroplast. Chloroplasts are large organelles that capture light energy. It contains two important components: thylakoids, flattened saclike membranes and stroma, fluid filled space outside the thylakoids
What are pigments? What s chlorophyll? Pigments are light absorbing colored molecules. Chlorophyll is the major pigment in plants, absorbs all colors except green
What is a stomata and what are they used for? Stomata are tiny openings used for gas exchange
Photons Sunlight particles
Photoexcitation Energy from photon causes electrons to shoot down thylakoids membrane
Photolysis Energy from electrons
Phosphorylation Electrons that provide energy to bind ADP and P creating ATP
