Photosynthesis & Cellular Respiration
Had a Biology Test, had to study.
Reactants (Inputs) of Photosynthesis
Water, sunlight, Carbon dioxide
Products (outputs) of Photosynthesis
Oxygen and Glucose
Reactants (Inputs) of Cellular Respiration
Oxygen and Glucose
Products (Outputs) of Cellular Respiration
Carbon Dioxide, water, ATP
Main purpose of Photosynthesis
light energy changed to chemical energy produces glucose
Main Purpose of Cellular Respiration
chloroplasts (plant cells)
Light-Dependent Reactions location
thylakoid membranes of chloroplasts - chlorophyll pigments
Light-Independent Reactions location
stroma of the chloroplasts
Cellular Respiration location
animal and plant cells (eukaryotic cells)
Krebs Cycle location
inner space of the mitochondria (matrix)
E T C (electron transport chain) location
inner membrane of mitochontria
Electron Carriers of Photosynthesis
Electron Carriers of Cellular Respiration
NADH (NAD positive) and FADH2 (FAD)
The Stages of Photosynthesis
1. Light-dependent Reaction: chlorophyll absorbs light energy to make carrier NADPH
2. Calvin cycle: Carbon Dioxide, ATP and NADPH are used to make glucose.
The First Stage of Cellular Respiration
Glycolysis: glucose is broken down into pyruvic acid + NADH + 4 ATP (net gain of 2 ATP)
The Second and Third Stages of Cellular Respiration (with oxygen present)
Krebs cycle: pyruvic acid is used to form NADH and FADH2 + 2 ATP
ETC: NADH and FADH2 and oxygen are used to form 32 ATP
The Fourth and Fifth Stages of Cellular Respiration (without oxygen present)
Lactic Acid Fermentation: pyruvic acid + NADH ---> lactic acid + NAD positive and allows glycolysis to continue.
Makes muscles sore and fatigued.
Alcoholic fermentation: pyruvic acid + NADH ---> ethyl alcohol + CO2 + NAD positive.
