Photosynthesis Flashcards
Metabolism
All chemical reactions in a cell
Metabolic Pathway
The product of one reaction is the substrate for the next reaction
Catabolic
Release of energy by breaking down larger molecules into smaller ones
Anabolic
Uses energy released by catabolic pathways to build larger molecules from smaller one
Photosynthesis equation
6 CO2 + 6 H2O + light —> C6 H12 O6 + 6 O6
Cellular Respiration equation
C6 H12 O6 + 6 O6 —> 6 CO2 + 6 H2O
Photosynthesis Defenition
The process by which autotrophs make food
Cellular Respiration
The process by which autotroph/heterotrophs use the product of photosynthesis to make energy
ATP
Most important biological molecule providing energy
Electron transport - Step 1
Light excites electrons and also causes a water molecule to split releasing an electron into the electron transport system.
Electron Transport - Step 2
Activated electrons are passed from one molecule to another molecule along the membrane.
Electron Transport - Step 3
Electrons get transferred to a protein called Ferrodoxin.
Electron Transport - Step 4
Ferrodoxin transfers electrons to the electron carrier NADP+, forming the energy - stored molecule NADPH.
2 products of Electron Transport
ATP and NADPH (used in phase 2)
Chemiosmosis
The mechanism by which ATP is produced as a result of the flow of ions down a concentration gradient.
