Question
Chapter 36, Problem 5P
Interpretation Introduction
Interpretation:
The role of light chain in myosin and kinesin should be determined.
Concept introduction:
The myosin is a type of motor filaments present in the eukaryotes. It is present in the muscles and help in muscle contraction. The kinesin is a class of motor protein in eukaryotic cells. They are powered by the ATP molecules in the cells and they move along the microtubule filaments.

Explain how gramicidin can forman ion channel when a typical membrane-spanning α-helix cannot (eg, glycophorin A).arrow_forward
