What is pore protein?
integral protein that embedded to the plasma membrane. Allow small substances to cross the plasma membrane.
What are functions of RNA in bacteria?
1) Acts as catalysts for most biochemical reactions 2) Acts as a carrier for amino acids during protein synthesis 3) Acts as a transmitter of genetic information to offspring 4) Acts as a template in protein synthesis.
Where does post transcriptional modification happen?
The first place that a translated protein is modified is in the lumen of the rough endoplasmic reticulum. This is generallyglycosylation, or the addition of sugar molecules to the protein. This happens when the translated protein enters the lumen of the ER through its pore. The signal sequence (very first part of a translated protein) enters the pore aided by the signal sequence recognition protein SRP. In the rER lumen the protein assumes its tertiary shape as well. Glycosylation also occurs in the Golgi apparatus, specifically, the first modification in the Golgi is in the first part of the Golgi, the CIS Golgi network. The Golgi packages and modifies the protein for their distribution.
What muscle cell protein acts as an ATPase enzyme?
myosin
Where does waste exit the paramecium?
The anal pore
What is pore protein?
integral protein that embedded to the plasma membrane. Allow small substances to cross the plasma membrane.
What allows the RNA to exit the nucleus?
mRNA exits the nucleus after it binds to TAP/p15 protein. This protein helps the mRNA through the hydrophobic nuclear pore. Other RNAs bind to Exportine-proteins, which help them to pass the pore.
When a receptor protein in a cell membrane acts as a enzyme the receptor protein does what?
When a receptor protein acts as an enzyme, the receptor protein activates a second messenger that acts as a signal molecule within the cell. Resources: HOLT Biology Textbook - 9th grade edition Chapter 4, Cells and Their Environment.
What is a protein that acts as hormone?
Insulin
RNA and other molecules leave the nucleus through the structure called?
The nuclear pore which acts as a gate keeper
What in the body acts like a protein?
Mitochondria
What is a protein that acts as an organic catalist?
First of all 'catalist ' is spelled as 'CATALYST'. Note the 'Y' in place of 'i'. A protein that acts as an orgsanic catalyst is an ENZYME.

1) Acts as catalysts for most biochemical reactions 2) Acts as a carrier for amino acids during protein synthesis 3) Acts as a transmitter of genetic information to offspring 4) Acts as a template in protein synthesis.
Why cant proteins and polysaccharides diffuse through the membrane like water does?
As the pore radius of the membrane approaches the protein radius, the mobility of the protein is significantly reduced
Neurotransmitters are released in a synapse and bind to?
a receptor structure in a ligand-gated sodium-ion pore. The receptor is like a cave which is an outer part of a protein structure which also has a tunnel which can be open or closed, and the presence of the neurotransmitter causes the tunnel (pore) to open.

What organelles acts as protein factories for the cells?
it's the ribosomes
