WHO WANTS TO PASS BIOLOGY? Chapter 8 : Cellular Energy WHO WANTS TO PASS BIOLOGY? What is the ultimate energy source for the cell? DNA AMP ATP WHO WANTS TO PASS BIOLOGY? Energy exists in all of the following forms EXCEPT: chemical energy mechanical energy thermal energy organic energy WHO WANTS TO PASS BIOLOGY? What are the two types of metabolic pathways? catabolic and antagonistic catabolic and anabolic catabolic and catatonic WHO WANTS TO PASS BIOLOGY? An autotroph Eats its food for energy Makes its food for energy Gets its energy from the soil WHO WANTS TO PASS BIOLOGY? A heterotroph eats its food for energy makes its food for energy gets its energy from the sun WHO WANTS TO PASS BIOLOGY? What does an anabolic pathway accomplish? builds up large molecules from smaller ones breaks down large molecules into smaller ones builds smaller molecules from larger ones WHO WANTS TO PASS BIOLOGY? What does a catabolic pathway accomplish? builds up large molecules from smaller ones breaks down large molecules into smaller ones builds smaller molecules from larger ones WHO WANTS TO PASS BIOLOGY? Photosynthesis is a(n) catabolic reaction anabolic reaction negative reaction WHO WANTS TO PASS BIOLOGY? Cellular respiration is a(n) catabolic reaction anabolic reaction negative reaction WHO WANTS TO PASS BIOLOGY? Why is photosynthesis and cellular respiration considered to be an energy cycle? because the products of photosynthesis are used as the reactants of cellular respiration because the products of cellular respiration are used as the reactants of photosynthesis because glucose and oxygen from photosynthesis are used in cellular respiration to make carbon dioxide and water because carbon dioxide and water from cellular respiration are used in photosynthesis to make glucose and oxygen all of the above WHO WANTS TO PASS BIOLOGY? Which describes the process of cellular respiration? anabolic pathway that breaks molecules into energy catabolic pathway that breaks molecules into energy catabolic pathway that builds molecules of stored energy WHO WANTS TO PASS BIOLOGY? Which describes the process of glycolysis? aerobic process that breaks down glucose anaerobic process that breaks down glucose anaerobic process that manufactures glucose Which describes the process of fermentation? aerobic process that manufactures pyruvate aerobic process that restores NAD+ supply anaerobic process that manufactures pyruvate anaerobic process that restores NAD+ supply WHO WANTS TO PASS BIOLOGY? Identify the products labeled A and B in the equation for photosynthesis: 6CO2 + 6H2O A+B A. C6H12O6 ; B. 6H2O A. C6H12O6 ; B. 6CO A. C6H12O6 ; B. 6O2 WHO WANTS TO PASS BIOLOGY? Which is an autotroph? daisy earthworm mushroom WHO WANTS TO PASS BIOLOGY? Where in the cell does the Krebs cycle occur? chloroplast cytoplasm mitochondrion WHO WANTS TO PASS BIOLOGY? Light-absorbing molecules such as chlorophyll are called pigments stomata thlakoids WHO WANTS TO PASS BIOLOGY? Which identifies the relationship between photosynthesis and cellular respiration? Both processes release energy for cell use. The products of one process are used as reactants by the other process. The reactants of one process are also the reactants of the other process. WHO WANTS TO PASS BIOLOGY? Which molecule is the most important biologically in that it provides organisms with chemical energy? ATT ADP ATP WHO WANTS TO PASS BIOLOGY? Which is recycled through the Krebs cycle? citric acid NADH Nucleic acid WHO WANTS TO PASS BIOLOGY? Which is formed during the light-independent phase of photosynthesis? ATP Glucose molecules NADPH WHO WANTS TO PASS BIOLOGY? Which of the following is a heterotroph? oak tree squash orca WHO WANTS TO PASS BIOLOGY? What is the chemical formula for cellular respiration? C6H12O6 + 6H2O 6CO2 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O 6CO2 + 6H2O C6H12O6 + 6O2 WHO WANTS TO PASS BIOLOGY? The first law of thermodynamics states: energy is created and destroyed energy cannot be created or destroyed energy comes from the sun WHO WANTS TO PASS BIOLOGY? Where in the chloroplast do the light reactions occur? a. stroma b. thylakoids c. inner membrane WHO WANTS TO PASS BIOLOGY? Where in the chloroplast do the lightindependent reactions occur? stroma thylakoids inner membrane WHO WANTS TO PASS BIOLOGY? What molecule is split in order for this process to occur? a. ATP b. thylakoids c. water WHO WANTS TO PASS BIOLOGY? In chemiosmosis, where in the chloroplast is ATP formed? thylakoid stroma electron transport chain WHO WANTS TO PASS BIOLOGY? What energy storing molecule is formed in the electron transport chain? ATP NADPH Glucose WHO WANTS TO PASS BIOLOGY? What energy storing molecule(s) are/is formed in chemiosmosis? ATP NADPH Glucose both a. & b WHO WANTS TO PASS BIOLOGY? A student is collecting the gas given off from a plant in bright sunlight at a temperature of 27°C. The gas being collected is probably a. carbon dioxide b. water vapor c. d. Oxygen WHO WANTS TO PASS BIOLOGY? Most plants appear green because chlorophyll a. absorbs green light b. c. reflect yellow light c. reflects green light WHO WANTS TO PASS BIOLOGY? Which of the following is the correct sequence of events in cellular respiration? a. Glycolysis ÿ fermentation ÿ respiration b. Krebs cycle ÿ electron transport ÿ glycolysis c. Glycolysis ÿ Krebs cycle ÿ electron transport WHO WANTS TO PASS BIOLOGY? The two main types of fermentation are called a. alcoholic and aerobic b. aerobic and anaerobic c. alcoholic and lactic acid WHO WANTS TO PASS BIOLOGY? How much ATP is produced in glycolysis? 2 32 36 WHO WANTS TO PASS BIOLOGY? . How much ATP is produced in the Krebs Cycle? 2 32 36 WHO WANTS TO PASS BIOLOGY? How much ATP is produced in the Electron Transport Chain? 2 32 36 WHO WANTS TO PASS BIOLOGY? Infer the economic importance of the process of fermentation. WHO WANTS TO PASS BIOLOGY? Deduce why a soccer player might feel soreness in his or her muscles during a game. How could the player relieve leg soreness?
