seminar 3 - substrate transport and storage at the cellular level Flashcards
what is the term for the diff types of transport across the cell membrane?
diffusion
what type of transport is osmosis?
passive transport
what is the correct name of the glucose transporter that is insulin-dependent?
GLUT4
GLUT2 is a glucose transporter that is found in the cell membrane of what tissues?
pancreas, liver and small intestines
do fatty acids only cross the membrane of skeletal muscle by passive transport/diffusion?
no
What type of transport is used to transport amino acids into skeletal muscle?
active transport
what is the scientific name for a liver cell?
hepatocyte
Fatty acids arrive at the site of an adipocyte packed in chylomicrons, or lipoprotein particles and have to be “unpacked” before they can transport into the cell. What is the name of the enzyme that unpacks free fatty acids?
Lipoprotein lipase
In comparison to healthy individuals, people with type 2 diabetes have…
Less GLUT4 and less translocation upon insulin activation
True or False: GLUT4 is translocated to the skeletal muscle membrane upon insulin activation, but not following an exercise stimulus.
false
what is a monocyte?
type of white blood cell (leukocytes) that play an important role in the immune system.
what is an adipocyte?
fat cell
