UNIT 3 CELL PHYSIOLOGY Flashcards
1
Q
Passive transport
A
no energy input required
- simple diffusion
- osmosis
- facilitated diffusion
2
Q
active transport
A
uses energy (ATP)
3
Q
how to cells produce ATP
A
- glycolysis (anaerobic)
- citric cycle
- mitochondrial electron transport chain
- ATP synthase
4
Q
phases of the cell cycle
A
G1 phase = normal cellular function
S phase = DNA replication
G2 phase = preparation for mitosis
M phase = nuclear and cytoplasmic division
5
Q
cyclins
A
proteins that monitor checkpoints of cell division
