Chapter 3 course packet Flashcards
Of the 6 kingdoms of life, which 2 are prokaryotic?
Eubacteria & Archaebacteria
Cell theory
1) All living things are composed of one or more cells
2) The cell is the smallest functional unit of life
3) All cells come from pre-existing cells
Cell structure
1) Plasma membrane
2) DNA region (nucleus)
3) Cytoplasm
This significance of cell (plasma) membrane function
- Diffusion
- osmosis
- facilitated transport
- active transport
- endocytosis and exocytosis
What are endocytosis & exocytosis?
Mass movement of materials into/out of cells
What are considered passive transport?
Diffusion, Osmosis, facilitated transport
What are considered active transport?
Active transport, Endocytosis, exocytosis
What are cell organelles
- Nucleus
- endoplasmic reticulum
- ribosomes
- golgi bodies
- vesicles
- mitochondria
What is the nucleus
Headquarters, it will govern what the cell will do
What is osmosis
The diffusion of water
What is facilitated transport
It needs the help of a protein to get across
What is active transport
It costs energy to go against the concentration gradient
What are the 3 stages of aerobic respiration
1) Glycolysis (in cytoplasm) 2 ATPs
2) Short prep steps & citric acid cycle 2 ATPs
3) Electron transport chain (taking the byproducts of the first 2 stages 32 ATPs
A typical total of 36 ATP’s
