Chapter 1 Low Energy State Flashcards
1
Q
What does a cell do if mutated?
A
Die or mutate
2
Q
What gene controls apoptosis?
A
p53
3
Q
What protein carries it out?
A
Cyclin D “Big D”
4
Q
What label is put on cells that should undergo apoptosis?
A
phosphatidlyserine
5
Q
What enzymes carry apoptosis out?
A
caspases
6
Q
What enzyme coats protiens for apoptosis?
A
ubiquitin
7
Q
Movement across membranes requires 3 things:
A
ATP, Calcium, microtubules
8
Q
First sign of cell injury
A
cell swelling
9
Q
Why do cells swell?
A
Na/K pumps don’t work. Na trapped in cell and Cl enters bringing water that causes swelling
10
Q
What two infections arise from low-energy state?
A
pulmonary (because cilia don’t have energy to clean out lung) and UTI (because cannot contract bladder to empty urine and expel microbes)
