Cell Processes Review S. Unit 3 Biology Mrs. Melino

#1 The usable form of energy produced by cellular respiration ATP DNA Glucose

#2 Organisms that make their own food Heterotrophs Consumers Autotrophs

#3 How do organisms get the ENERGY from ATP? By photosynthesizing By breaking the high-energy bond between the last two phosphates By recharging it’s batteries

#4 ADP can be reused to store more energy and released when required. True False

#5 What is the name of the enzyme that breaks the bond in ATP? ATPsynthase ATPase ADPuse

#6 How is ATP remade? Enzyme ATPsynthase Enzyme ATPase It can’t be remade

#7 When is ATP made in the body? During photosynthesis During cellular respiration During mitosis

#8 Identify the inputs for cellular respiration (what is taken in)? Oxygen and Carbon Dioxide Carbon Dioxide and Glucose Glucose and Oxygen

#9 Breaking down ONE glucose molecule can result in up to _______ ATP molecules 2 6 38

#10 Which of the following is NOT a stage of cellular respiration Light independent reaction Glycolysis The Krebs Cycle

#11 Where does Cellular Respiration take place? Mitochondria Cytoplasm and Mitochondria Chloroplast

#12 Which form of respiration DOES NOT require oxygen? Aerobic Anaerobic Krebs

#13 What are the products of cellular respiration? C6H12O6 & O2 CO2 & H2O H20 & C6H12O6

#14 Where does Photosynthesis occur? Mitochondria Cell Membrane Chloroplast

#15 What are the reactants (inputs) for photosynthesis? CO2 and C6H12O6 CO2 and H2O C6H12O6 and H20

#16 Identify the products of Photosynthesis CO2 & H2O C6H12O6 & O2 C6H12O6 & H20

#17 Which of the following is a raw material for photosynthesis? O2

#18 Photosynthesis produces _________ as a waste product Oxygen Carbon Dioxide Glucose

#19 Plants need _________ to photosynthesize Light Oxygen Glucose

#20 _____________ absorbs the light energy which plants need to build sugars from water and carbon dioxide Stomata Chlorophyll Cellulose

#21 This American chemist received the Nobel prize for discovering the pathway of photosynthesis Melvin Calvin Joseph Priestly Han Solo

#22 Identify Photosynthesis 6CO2 + 6H2O  C6H12O6 + 6O2 C6H12O6 + 6O2  6CO2 + 6H2O + energy 6CO2 + C6H12O6  energy

#23 Where do plants exchange gases? Stems Flowers Stomata

#24 The rate of photosynthesis may be limited by: Low temperature Shortage of carbon dioxide Shortage of light All of the above

#25 Some cell types contain thousands of mitochondria. These cells are likely to use large amounts of which of the following? A. ATP B. carbon dioxide C. DNA D. nitrogen

#26 In periods of hot, dry weather, the pores on the leaf surfaces of most plants close in order to reduce water loss during the day. When these pores are closed, plants cannot take in carbon dioxide. As a direct result, the rate of which of the following processes decreases? A. cellular respiration B. nitrogen fixation C. photosynthesis
