Cells and Energy

Respiration and Photosynthesis Examined

QuestionAnswer
Reactants for photosynthesis Carbon Dioxide and Water
Carries energy from light reactions to the Calvin Cycle (2) NADPH and ATP
Location of chlorophyll and the light reactions Thylakoid
Products of photosynthesis Glucose and Oxygen
Equation for photosynthesis (light) + 6CO2 +6H2O -> C6H12O6 + 6O2
Process of taking carbon dioxide gas and creating an organic molecule carbon fixation
Stage of photosynthesis where oxygen is released light reactions
Stage of photosynthesis where carbon fixation happens Calvin cycle
Stage of photosynthesis where water is split Light reactions
Organisms that can produce their own glucose from abiotic sources Producers or Autotrophs
Organisms that take glucose from other organisms Consumers or Heterotrophs
Definition of photosynthesis Process that creates glucose using light energy
Definition of cellular respiration Process of breaking down glucose to produce ATP
Energy carrying monomer that transfers energy between organisms glucose
Polysaccharides that contain glucose Starch, glycogen, cellulose
Polymer that plants often use to store the glucose they make starch
First stage of cellular respiration Glycolysis
Small, energy storing and releasing molecule used inside organisms for reactions ATP
Define activation energy Energy needed to start a reaction
What is a catalyst Something that lowers activation energy to speed up reactions
Organic molecules that act as catalysts enzymes
Location of Glycolysis Cytoplasm (Cytosol)
Products of Glycolysis 2 ATP, NADH, 2 Pyruvates (pyruvic acid)
2nd stage of aerobic respiration Kreb's Cycle (Citric Acid Cycle)
Molecule that combines with Carbon Dioxide in the Calvin Cycle RuBP
Enzyme that helps carbon fixation to occur RuBisCo
Location of the Citric Acid Cycle Mitochondria
Products of Kreb's Cycle 2 ATP, NADH, FADH2
3rd stage of aerobic respiration Electron Transport Chain
Process of attaching a 3rd phosphate to ADP Oxidative Phosphorylation
Is transferred between proteins in the ETC electron
Is actively pumped against a gradient during the ETC hydrogen ions
Enzyme that helps create ATP ATP Synthase
Reactants of aerobic respiration Glucose and Oxygen
Products of aerobic respiration ATP, Carbon Dioxide, and Water
Glucose is first broken down in this stage Glycolysis
Carbon Dioxide is released in this stage of respiration Kreb's Cycle
Oxygen is required for this stage of respiration ETC
Water is produced in this stage of respiration ETC
Producing ATP from glucose when oxygen is NOT available anaerobic respiration
Types of anaerobic respiration Lactic Acid Fermentation and Alcohol Fermentation
Stage that is repeated in anaerobic respiration Glycolysis
Becomes Lactic Acid Pyruvate
Pyruvic Acid becomes this when yeast do anaerobic respiration Ethanol
Waste product of aerobic and anaerobic respiration Carbon Dioxide
Formula for Cellular Respiration C6H12O6+6O2->6CO2+6H2O+(ATP)
Endosymbiotic Theory Theory that mitochondria and chloroplasts were once bacteria that got into another prokaryotic cell, survived, and developed a symbiotic relationship
Evidence for Endosymbiosis 1) They have their own DNA, 2) Their DNA is similar to other bacteria, 3) They divide on their own (not with the rest of the cell), 4) The way they divide is similar to bacteria
Why is it reasonable to think mitochondria developed before chloroplasts All organisms have mitochondria, but only producers have chloroplasts
What happens to ATP after it is used It becomes ADP and returns to the mitochondria to "recharge"
Form of anaerobic respiration done by humans Lactic Acid Fermentation
Organelle responsible for cellular respiration mitochondria
Organelle responsible for photosynthesis chloroplast
Pigment that absorbs light (except green) in photosynthesis chlorophyll
