Peroxisomes & Mitochondria

Question 0

Function of peroxisomes

Answer 0

Breaks down phytanic acid by α-oxidation, breaks down very long chain fatty acids by β-oxidation which produces H2O2, catalase degrades H2O2 yielding water and oxygen, detoxification, biosynthesis of myelin precursor, bile acids and cholesterol

Question 1

Peroxisome

Answer 1

Small, spherical organelle responsible for producing and breaking down hydrogen peroxide; important for breakdown of fatty acids, detoxification, synthesis of cholesterol, bile acids and myelin

Question 2

Mitochondria

Answer 2

Ubiquitous organelles responsible for energy production (ATP), calcium storage, regulation of programmed cell death (apoptosis), catabolism of carbohydrate, lipid and protein derivatives. Have their own endogenous DNA genome,

Question 3

Functions of mitochondria

Answer 3

ATP synthesis, catabolism-oxidizes long chain fatty acids and private into acetyl coa, calcium homeostasis, regulation of apoptosis
