Verified step by step guidance
1
Understand the role of membrane proteins: Membrane proteins are integral or peripheral proteins that are part of, or interact with, the cell membrane. They play various roles in cellular processes.
Identify the functions of membrane proteins: Common functions include acting as channels or transporters to facilitate the movement of substances across the cell membrane, serving as receptors for signal transduction, providing structural support, and participating in cell recognition.
Analyze the given options: Evaluate each option to determine if it aligns with the known functions of membrane proteins.
Option 1 - Facilitating the transport of substances across the cell membrane: This is a well-known function of membrane proteins, as they often form channels or carriers that help move ions and molecules across the membrane.
Option 2 - Producing ATP, Option 3 - Storing genetic information, Option 4 - Synthesizing lipids: These functions are not typically associated with membrane proteins. ATP production is primarily a function of mitochondria, genetic information is stored in DNA within the nucleus, and lipid synthesis occurs in the endoplasmic reticulum.
