Final Study Guide Part II Flashcards
Defining characteristic of prokaryotic cells
Lacks a nucleus and membrane bound organelles
Characteristics of plant and animal cells
Genetic material contained in a membrane bound nucleus
Capable of greater variety of activity
Contain numerous specialized organelles
Uni or multicellular
Ribosomes
Protein synthesis
Golgi apparatus
Sorts and packages products for export
Mitochondria
Energy production, cellular respiration
Lysosomes
Waste removal
Chloroplasts
Photosynthesis occurs here
Centrioles (centrosomes)
Provides structure and aids in cell division by pulling chromatids apart
Active transport
Movement from an area of low concentration to high concentration with the use of a protein
Requires energy
Diffusion
Molecules move from an area of high concentration to an area of low concentration
Osmosis
Movement of water across a semi-permeable membrane
Light reaction of photosynthesis
Light is absorbed by photosystems which become “photoexcited”. Electrons get stripped from PII and travel ETC to produce ATP
Electrons stripped from PI travel another ETC, get picked up by NADP+ to produce NADPH
Calvin Cycle
CO2 is input, carbon fixation occurs— PGAL synthesis occurs and uses ATP and NADPH—1 PGAL exits to form glucose
Where does light reaction occur?
What are the reactants and products?
Occurs in the thylakoids
Takes in light and h2o
Puts out NADPH and ATP (energy)
Where does the Calvin cycle occur?
What are the inputs and outputs?
Occurs on the stroma
Uses CO2, ATP and NADPH to produce glucose
