... to the end where there is the flagella for motility. The egg cell is full of maternal mRNA that are silenced till fertilization. It also has vesicles just under the plasma membrane that will release enzymes upon one sperm contact and prevent polyspermy from happening. A release of Ca ++ happens ...

... neuron. 2. Sometimes it diffuses out of the synaptic cleft. 3. It may be reabsorbed by the presynaptic neuron and packaged again in the synaptic vesicles. 4. It may be (occassionaly) absorbed by the Glia. As you can see malfunctioning in all of the above can cause neurotransmitter to accumulate ...

the molecular basis of the two hormones is also quite different. ADH induces the fusion of intracellular vesicles carrying acquaporins with the PM, increasing the water that can be transported through the membrane. Aldosterone is a steroid, so what it does is to interact with ...

Just wanted to add that proteins incorporate many sugars for signaling purposes: either glycoproteins or proteoglycans. For example: Secretory vesicles in the Golgi cisterna use mostly mannose, galactose, and NAG (N-Acetlyglucosamine) to make the necessary glycoproteins for export. Oh, and all ...
