Difference between ion pump and channel?
An ion channel is a passive transport and does not require energy for it to occur. An ion pump, meanwhile, is an active transport and requires an input of energy for it begin.
What can be opened or closed in a cell membrane?
Gated Ion Channel. Not sure about the answer
Are gated channels are always open?
Yes, it can a gated ion channel is opened when a signal molecule binds to a receptor protein causing the receptor protein to open the ion channel through the cell membrane and after this process the ion channel is closed once again to prevent various molecules to enter the cell.
Ion channel that are always open are called?
leak channes
A “ligand-gated” ion channel is one that will open in response to:?
A specific molecule binding to it
What part of the cell stores calcium ion?
the smooth endoplasmic reticulum
What does the soft endoplasmic reticulum do?
Smooth Endoplasmic reticulum creates steroids and stores ions. The ion storage is important to keep the correct level of nutrients within the cell. Ion storage is like our fat cells holding on to sugars for when you need them.
What transport protein allows ions to pass through the cell membrane?
Ion Channels allows ions to pass through the cell membrane.
What are the general functions of endoplasmic reticulum?
Two general functions are the modification and folding of proteins in the lumen of the rough ER and the manufacture of lipids in the smooth ER. Also has the important job of calcium ion storage as these ions are important second messengers in cell signaling.
What organelle releases calcium?
The endoplasmic reticulum has a store of calcium ions, Ca 2+, that it releases as second messengers in signalling transduction. Also the scarcoplasmic reticulum releases this ion in the process of sarcomere contraction.
What is immediate source of calcium ion for muscle fiber?
There is some calcium outside the cell but the bulk of it comes from intracellular stores.
Is the concentration of calcium ion greater in the sarcoplasmic reticulum or sarcoplasm of a resting muscle?
The Ca2+ ion concentration of the sarcoplasmic reticulum will be greater in a resting muscle
Which ion is stored in the sarcoplasmic reticulum?
Calcium (Ca+2)
What channel is ION on cablevision?
Channel 3
What channel is ion on direct tv?
ION is on channels 216 and 217. It is available with our 120 programming packages and above.
What substance is released into the sacroplasm reticulum causing muscle relaxation?
calcium ion
Is ion channel on Time Warner cable so Calif area?
YES! Time Warner Cable has Ion Channel. Regular is channel#30 and in HD it is channel#410
