Respiration and Photosynthesis Flashcards
If the products have more energy than reactants….
Then energy must be supplied
If the products have less energy than reactants…
Then energy must be released
Activation Energy
The energy must be processed by a molecule in order for it to undergo a chemical reaction
Catalysts (lower/increase) activation energy
Lower
Active Site
The region of an enzyme surface to which a specific set of substrates bind
Why don’t reactions go out of control?
Feedback Inhibition
Feedback Inhibition
The control mechanism; an increase in the concentration of the same molecule inhibits the synthesis of that molecule
ATP is made in the….
Mitochondria/Chloroplasts
Simple Sugar
3-6 carbons
Monosaccharides
Simple Sugar
Transport Molecules
Disaccharides
Lactase Enzyme Inefficiency
Lactose Intolerance
Storage/Structural Molecules
Polysacchardies
Long term energy storage
lower water content
How are polysaccharides stored in plants?
Starch
Cellulose
How are polysaccharides stored in animals?
Glycogen
Structural
Plant cell walls
Most organisms cant break the beta bond (symbiotic gut bacteria)
Cellulose
Structural
Modified form of Cellulose
Used by arthropods (insects, crustaceans) and fungi
Chitin
_____ goes through Cellular Respiration
Hetertrophs
Complete oxidation of glucose to extract energy from chemical bonds
Cellular Respiration
Loses electrons
Oxidized
Accepts/Gains electrons
Reduced
Paired rxn in living systems; an electron is lost by one atom are gained by another atom
Redox Rxns
Another name for Redox Rxns
Oxidative-Reduction Rxns
Used by cells to take energy (ATP) from food
Facilitated by enzymes
Redox Rxns
