#1
Front (Question)

Difference between integral and peripheral proteins?

Back (Answer)

Integral = permanent, span membrane; peripheral = temporary, surface-attached.

#2
Front (Question)

Function of channel proteins?

Back (Answer)

Form pores for ions/water to pass by facilitated diffusion.

#3
Front (Question)

Function of carrier proteins?

Back (Answer)

Transport specific molecules via facilitated diffusion or active transport.

#4
Front (Question)

Function of receptor proteins?

Back (Answer)

Bind signaling molecules (hormones, neurotransmitters) to trigger cell responses.

#5
Front (Question)

Example of transporter protein?

Back (Answer)

GLUT1 glucose transporter; moves glucose into mammalian cells.

#6
Front (Question)

Location of glycoproteins and glycolipids?

Back (Answer)

Exterior of plasma membrane; attached to proteins (glycoproteins) or lipids (glycolipids).

#7
Front (Question)

Function of glycoproteins?

Back (Answer)

Cell-cell communication, adhesion, receptor functions, immune recognition.

#8
Front (Question)

Function of glycolipids?

Back (Answer)

Membrane structure, tissue formation, immune recognition.

#9
Front (Question)

How do glycoproteins relate to blood groups?

Back (Answer)

Oligosaccharides on RBC surface act as antigens; determine ABO blood type.
