Chapter 14: Problem 24

Retinal is a. a derivative of vitamin A. b. sensitive to light energy. c. a part of rhodopsin. d. found in both rods and cones. e. All of these are correct..

Short Answer

Expert verified
All of the given statements about retinal are accurate, so the correct answer is E. Retinal is a derivative of vitamin A, sensitive to light energy, a part of rhodopsin, and found in both rods and cones.

Step by step solution

01

Analyze Statement A

Retinal is a derivative of vitamin A. This statement is true because retinal is an essential component in the visual cycle, synthesized from Vitamin A (Retinol).
02

Analyze Statement B

Retinal is sensitive to light energy. This statement is also true since retinal is responsible for sensing light energy and initiating the process of vision in the rod and cone cells of the eye.
03

Analyze Statement C

Retinal is a part of rhodopsin. This statement is correct as well. Rhodopsin is a light-sensitive receptor protein found in the rod cells, and it contains a molecule of retinal bound to a protein called opsin.
04

Analyze Statement D

Retinal is found in both rods and cones. This statement is true. Retinal is a crucial component in both rod and cone cells of the retina.
05

Analyze Statement E

All of these are correct. Since we have determined that each of the statements A, B, C, and D are correct, the answer to this question is statement E. All of the given statements about retinal are accurate.
