An exocytotic vesicle is a membrane bound vesicle containing contents intended for release into the external environment. The vesicle will ultimately be fused with the cell membrane when its contents are released.

What is a heterogeneous mixture and what are some examples?
In a heterogeneous mixture components are not thoroughly mixed and the mixture properties have a gradient, components are visicle, many phases exist, the material is not uniform. Examples: a rock, a soup, soil, dirty water, wastes, non miscibles liquids etc.
Information is passed through what neurons?
Neurons are involved in signaling; the propagation of action potentials and the release of substances that effect other tissues. It is information in the wider context of the word since the individual signal only has significance in relation to the activities of other neurons as well.
What is synaptic facilitation?
an action will happen cause of axo-axonal syanapse,which can facilitate the nerve impulse transmitting from presynaptic membrane to post synaptic membrane. In the axo-axonal synapse one axon is secreting serotonin which can influence to close some of K+ channels in the other neuron to maintain a prolonged action potential by slowing down the repolarization. as long as action potential is there it can stimulate the presynaptic membrane to release neurotransmitters towards postsyanptic membrane so prolonged action potential will help to stimulate more the Post synaptic membrane and give a strong impulse this is called presynaptic facilitation
What would you expect to find in exocytotic vesicles?
You would expect to find fluids inside of the exocytotic vesicles which will then move to the membrane to release the fluids on the outside...

What happens to a protein molecule after it has been translated?
it can undergo activation into a functional protein through clevage of certain amino acid sequencies. a amino acid sequence primary structure can fold to form the secondary and tertiary sturcture and forming bonds. splicing (Thats what the protein undergoes) to form functional protein.Also their is processing such as glycosylation in the ER to help with protein folding into functional enxymes.

What are the parts of the endomembrane system?
There are ten parts of the endomembrane system: Nuclear envelope, nuclear pore, ribosomes, smooth indoplasmic rediculum, secretory vesicle, lysosome, plasma membrane, and the Golgi apparatus. The endomembrane system during carposporogenesis inChondria tenuissima was studied using electron microscopy and histochemistry. Profiles of the nucleus are convoluted, resulting in a highly increased surface area. Stacked cisternae are found within the peripheral part of the nucleus. Vesicles, tubules and membrane bound fibrillar bodies occur within the nucleoplasm. The endoplasmic reticulum surrounds the nuclear envelope.The endoplasmic reticulum and the Golgi apparatus, together with small transition vesicles, represent a functional unit. They form two different secretory substances during carposporogenesis. In young stages, carbohydrates are produced by normal dictyosomes within large, normal exocytotic Golgi vesicles. They do not react positively with PAS or Thiéry method and are believed to represent cell wall material. In later stages, the central area of the Golgi cisternae becomes filled with electron dense material. The individual cisternae are transformed into cored vesicles at the trans-face of the dictyosomes. The dense core of the vesicles is proteinaceous and stains with coomassie brilliant blue R. The peripheral fibrillar material is polysaccharidic and reacts positively using the Thiéry method. The contents of the cored vesicles are believed to participate in carpospore attachment. The ER gives rise to cytolysosomes in which starch grains are sequestrated and digested. Mucilaginous sacs seem to be similarly formed.
Describe how a cell produces and releases proteins?
DNA transcribed into mRNA and then translate into proteins. Proteins moved into endoplasmic reticulum and transported to the Golgi body for further modification and package into exocytotic vacuoles. Release by exocytosis.First,DNA -> mRNA -> ProteinThe cell produces proteins by a process called translation. mRNA is translated at the ribosome into proteins. Typically for proteins that are actively transported out of the cell, the proteins are created and inserted into the endoplasmic reticulum. The endoplasmic reticulum buds off and is processed through the Golgi apparatus where the proteins are sorted and processed. The sorting of the proteins allows the proteins that are targeted for exocytosis to be carried in vesicles to the cell membrane (by a transport protein) where they are released.Each step involves budding, transport, and docking of vesicles which all involves use of ATP thus the process is very ATP dependent and is considered active transport.FYI, Passive Transport can only occur DOWN a concentration gradient.by the chromosomes and when you eat you get proteinsthe cell produces proteins by the things you eat.it releases it when you use the bathroom
What is the role of fatty acids in the body?
EFAs are also used by the body to produce a class of hormone-like substances called prostaglandins, which are key to many important processes.
