Photosynthesis and Cellular Respiration (Instruction)
Overall photosynthesis reaction equation
6CO2 + 6H2O + energy -> 6O2 + C6H12O6
Overall cellular respiration reaction equation
6O2 + C6H12O6 -> 6CO2 + 6H2O + energy
Photosynthesis and cellular respiration both use
ATP: Cellular respiration and photosynthesis produce and use ATP to carry energy for the various reactions within each process.
Definition of Adenosine triphosphate
Adenosine triphosphate (ATP) is a high-energy storing molecule in cells; composed of one adenosine molecule (adenine and ribose sugar) and three phosphate groups, it is present in all living organisms and is used to fuel activities within a cell.
Change in gases inhaled and exhaled indicate
Amount of cellular respiration taking place.
Preformed by producers
Both (Photosynthesis and Cellular respiration)
Which characteristics do photosynthesis and cellular respiration have in common? Check all that apply.
Both processes involve a cycle of chemical reactions. Both processes involve energy conversions. Both processes use and produce ATP. Both processes use an electron transport chain.
Electron transport chain
Both reactions use carrier molecules to transport electrons
Cellular respiration creates a net positive amount of ATP after
Breaking down glucose
Photosynthesis includes the
Calvin Cycle (Carbon dioxide coming in and glucose, sucrose, and others coming out)(Uses ATP)
Light-independent reactions
Calvin cycle uses energy in ATP to add carbon dioxide to carbon-based molecules to make glucose.
The products of cellular respiration are
Carbon dioxide and Water
The reactants of photosynthesis are
Carbon dioxide and Water
Preformed by consumers
Cellular respiration
Releases energy in the form of ATP
Cellular respiration
Which process occurs in the mitochondrion organelle?
Cellular respiration
Focus on Cellular Respiration
Cellular respiration breaks down glucose to obtain usable energy.
Definition of Cellular Respiration
Cellular respiration is the process that breaks down glucose to provide energy in the form of ATP for metabolic processes. (Used by producers and consumers)
Muscles use
Cellular respiration to release energy.
Which sentences describe the differences between photosynthesis and cellular respiration? Check all that apply.
Cellular respiration uses oxygen as a reactant and photosynthesis does not. Cellular respiration produces excess ATP and photosynthesis does not. Cellular respiration is preformed by consumers and photosynthesis is not. Cellular respiration releases energy from glucose molecules and photosynthesis does not.
What molecule that captures light energy in photosynthesis gives plants their color?
Chlorophyll
Photosynthesis occurs in the
Chloroplast
Light-dependent reactions
Chloroplasts capture solar energy, water molecules are split, electrons are transported, H+ ions are released, and ATP is made.
Electron transport chain
Electrons transport H+ ions across a membrane. H+ ions then produce more ATP and combine with oxygen to form water.
Krebs cycle
Forms citric acid and breaks it down to form carbon dioxide and make ATP.
The products of photosynthesis are
Glucose and Oxygen
The reactants of cellular respiration are
Glucose and Oxygen
Where does photosynthesis occur in the biosphere? Check all that apply.
In producers
Where does the cellular respiration occur in the biosphere? Check all that apply.
In producers In consumers
Cellular respiration includes the Krebs cycle.
Krebs Cycle (Pyruvic acid comes in and carbon dioxide comes out)(Release ATP)
Cellular respiration occurs in the
Mitochondrion
Check the box next to the process or processes used by the organism listed.
Oak tree, Seaweed, Grass = Cellular Respiration and Photosynthesis because they're producers. Housefly, Rabbit, Crab = Cellular Respiration because they're consumers.
Cellular respiration requires
Oxygen and releases carbon dioxide.
Stores energy in glucose molecules
Photosynthesis
Focus on Photosynthesis
Photosynthesis captures energy from the Sun and stores it as glucose.
Definition of photosynthesis
Photosynthesis is the process by which green plants, algae, and some bacteria capture light energy to form simple sugars using water and carbon dioxide and release oxygen gas as a byproduct. (Used by producers)
