Question

Carrier molecules that bring materials into cells are A. Lipids B. Proteins C. Glycogen D. Phospholipid

Answer 1

A Liquids

Explanation:

This is because in our stomach food is converted into liquid form by the digestive enzymes, acid etc..

Answer 2

Carrier molecules that bring materials into cells are B. Proteins.

What is the carrier molecule called?

• Usually, the movement of other biological substances like proteins, DNA or RNA, electrons, or protons, including ions, involves the use of a carrier molecule.
• For instance, carrier proteins can move through the cell membrane other substances like ions, sugar, fat, or peptides.
• Since they can easily undergo oxidation and reduction, carrier molecules—typically proteins attached to a nonprotein group—allow electrons to move freely throughout the system.
• Flavoproteins (such as FAD), cytochromes, iron-sulfur proteins (such as ferredoxin), and ubiquinone are the four different types of carriers.
• The glucose transporter is an illustration of a carrier protein utilized in assisted diffusion.
• A group of similar carrier proteins known as glucose transporters carries glucose across membranes.
• Since glucose is the main energy supply for cells, this function is crucial to their survival.
