Study Notes
Beta-Oxidation
- The enzyme responsible for the oxidation of acyl CoA during beta-oxidation is not specified (need more information).
- The product formed after the hydration step in beta-oxidation is not specified (need more information).
- The step in beta-oxidation that generates NADH is not specified (need more information).
- The final reaction in beta-oxidation is not specified (need more information).
- It takes 7 cycles of beta-oxidation to yield 8 acetyl CoA from palmitoyl CoA.
Visual Cycle
- The molecule responsible for the isomerization of all-trans retinal to 11-cis retinal in the visual cycle is not specified (need more information).
- The primary event in the visual cycle when exposed to light is the isomerization of 11-cis retinal to all-trans retinal.
- The conversion of all-trans retinol to all-trans retinal occurs in the retina.
- The molecule that combines with opsin to regenerate rhodopsin in the visual cycle is 11-cis retinal.
- Most of the all-trans-retinol in the visual cycle is either reduced back to retinol or transported to the RPE for re-isomerization and recycling.
