Unit 2
-
-
-
-
Plasma membrane
-
Semi-permeable membrane
small, hydrophobic, nonpolar molecules can go through
-
-
Passive transport
-
diffusion, osmosis, facilitated transport
-
diffusion allows gas exchange to occur between the lungs, blood, and cells

Unit 4
-
Cell communication
-
Multi-celled orgnanisms
signal transduction pathways coordinate the activities within individual cells that support the funciton of the organism as a whole.
cell junctions connect the cytoplasm of adjacent cells and allow material to be transported between cells
-
-
-
-
-
-
-
-
cell signaling, both prokaryotes and eukaryotes, occurs via signal transduction pathways.
Homeostasis: ability of an organism to maintain a stable internal environment despite changes in external conditions.
Unit 3
Photosynthesis
-
-
-
-
-
-
-
-
-
C3, C4, CAM plants
C3: rice, wheat, soybeans (3-carbon compound)
-
-
-
Energy
-
-
-
-
ATP
Adenosine + Triphosphate
ATP drives an endergonic reactions by phosphorylation, transferring a phosphate group
Cellular respiration
glycolysis
-
-
in cytoplasm, input = glucose, output= 2 ATP, 2NADH
pyruvate oxidation
pyruvate --> acetyl coA
In mitochondrial matrix, input=pyruvate, output= 2 Co2, 2 NADH, 2 acetyl coA
