Transport across the capillaries

T/F regarding facilitated diffusion,

• Is occur according to the concentration gradient.

• Is ATP dependent

• Always require proteins

• Rate of diffusion is higher than simple diffusion

• Rate of diffusion is higher than active transport

T/F regarding transport across cell membrane;

• Oxygen can cross the cell membrane without ATP

• GLUT transport glucose as secondary active transport.

• SGLT transport glucose as secondary active transport.

• Secondary active transport is independent of carrier proteins.

• Primary active transport is independent of carrier proteins.

T/F regarding diffusion,

• Glucose can cross the plasma membrane by diffusion.

• Water can diffuse through aquaporin channels.

• Diffusion of carbonic acid is facilitated by dissociation it in to HCO3- & H+

• Slower than active transport

• Diffusion is the main mode of transfer of O2 across the alveolar capillary membrane

Regarding Na+ K+/ ATPase pump,

• Is energy dependent

• Is transporting according to the concentration gradientnt

• Is transport Na+ from outside to inside to the cell

• Is transport K+ from outside to inside to the cell

• Is a saturable tranporter

What are the true examples of transport methods

• Na+ K+/ATPase pump - Primary active transport

• Na+ K+/ATPase pump - Secondary active transport

• Na+ K+/ATPase pump - Symport( co transport )

• Na+ K+/ATPase pump - Antiport( counter transport )

Regarding the above method of transport

• Glucose transport by SGLT is an example.

• Na+ Transporter across the cell membrane is an example.

• None-polar molecules can transport in above method

• Is using energy indirectly

• Occurs at alveolar membrane

T/F

• Green - Symport transportation

• Pink - Uniport transportation

• Pink - Na+ leakage channels is a example

• Green - GLUT Glucose transportation is a example

• Yellow - Na+ K+ pump is a example

T/F regarding above transport method

• Not use ATP

• Glucose does not use ATP directly.

• Seen in proximal convoluted tubule

• Seen in small intestine

• Is slower than GLUT transporters
