Q

Process of Oxidative Phosphorylation

A

- Creates a proton gradient
- Protons flow back into the matrix via ATP synthase, producing ATP
- Oxygen accepts electrons and protons to form water (H₂O)

158
Q

Goal of cancer cells

A

-survival, proliferation
-“Normal” cells require complex growth process, environment, etc.
-CA cells immortal; infinite divisions possible & always dividing
-CA cells secrete their own growth factors
-Loss of contact inhibition (auto stop): grow regardless of density/crowding
-Non-encapsulated, invade/destroy neighboring tissue
-Metastasis to body
-Loss of anchorage dependence: CA cells grow not attached to anything
-cancer cells can divide indefinitely due to the activation of telomerase enzyme that maintains telomere length.

159
Q

165
Q

Cancer Growth/Proliferation Influences:

A

-Amount of cells actively dividing at any given time compared to normal cells.

166
Q

Direct Invasion:

A

-Cancer cells invade adjacent tissues
-Secrete enzymes that break down surrounding structures
-Difficult to define margins/edges (no capsule)

167
Q

-Tumor cells can shed into nearby body cavities causing formation of new tumors in those spaces.

A

Seeding:

168
Q

Metastasis Spread:

A

-Spread from primary/origin tissue to secondary site/tissue
-Cancer cells break away from primary site, travel to other tissue
-Lymphatic spread: lymph nodes typically first site of spread
