Practice Questions What do living things do to energy? They transform it Why do living transform energy? To make ATP A form of energy the cell can use How is ATP used? To grow To make protein To do A.T. To repair injury What type of energy is circled below? Chemical energy What type of energy is circled below? ATP energy What type of energy is circled below? Light energy What process is circled below? Cellular respiration A.K.A. burning glucose Where in a cell does cellular respiration occur? Mitochondria What process is circled below? Photosynthesis Where in a cell does photosynthesis occur? Chloroplast Which part of this diagram is performed by heterotrophs? Cellular respiration ONLY Which part of this diagram is performed by autotrophs? All of it (photosynthesis AND cellular respiration) Which process is performed by both autotrophs and heterotrophs? Cellular respiration Explain WHY both autotrophs and heterotrophs perform cellular respiration. To get ATP A form of energy cells can use Identify the type of organism shown below, and state whether it is an autotroph or a heterotroph. Animal Plant Heterotroph Fungus Green Protist Non-green Protist Cyanobacteria Identify the type of organism shown below, and state whether it is an autotroph or a heterotroph. Animal Plant Autotroph Fungus Green Protist Non-green Protist Cyanobacteria Identify the type of organism shown below, and state whether it is an autotroph or a heterotroph. Animal Plant Autotroph Fungus Green Protist Non-green Protist Cyanobacteria Identify the type of organism shown below, and state whether it is an autotroph or a heterotroph. Animal Plant Heterotroph Fungus Green Protist Non-green Protist Cyanobacteria Identify the type of organism shown below, and state whether it is an autotroph or a heterotroph. Animal Plant Autotroph Fungus Green Protist Non-green Protist Cyanobacteria Identify the type of organism shown below, and state whether it is an autotroph or a heterotroph. Animal Plant Heterotroph Fungus Green Protist Non-green Protist Cyanobacteria Identify the type of organism shown below, and state whether it is an autotroph or a heterotroph. Animal Plant Autotroph Fungus Green Protist Non-green Protist Cyanobacteria Explain how cyanobacteria is different from other autotrophs. Prokaryotic autotroph Which molecule is larger? Glucose Which molecule contains more energy? Glucose Which molecule is used by cells to do work? ATP Where is energy stored in ATP? In the bonds between phosphate groups How is energy released from this molecule? When the bond between phosphate groups breaks This cell contains glucose. If this is an autotrophic cell, where did the glucose come from? photosynthesis If this is a heterotrophic cell, where did the glucose come from? Eating Identify the energy-requiring process circled below. Active transport Explain why the cell cannot use glucose to power AT. Too big Too much energy Identify the process circled below. Cellular respiration Explain why this process occurs. To transform glucose into ATP Predict where the ATP will go next. To the protein pump Explain how energy is released from the ATP. The bond between phosphate groups breaks Explain how the released energy is used. Used by the protein pump to do A.T. Explain how the release of energy changes ATP. Turns it into ADP Predict where ADP will go next. Back to the mitochondria To get re-charged Explain how ADP gets re-charged. Absorbs energy Adds a phosphate group Becomes ATP Since ADP can be re-charged, the process can be described as a cycle .v ADP can be re-charged. The process that re-charges ADP is cellular respiration.
