TEMPURATURE:
Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working.
pH:
Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.
DIFFERENT SUBSTRATES:
Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.
I got these explanations from khan academy :)
Answer:
Explanation:
TransA can be found in the plasma membrane, while TransB is found in the cytoplasm, according to the immunofluorescence localization test analysis. There are two main varieties of serotonin transporters in the neural system when it comes to serotonin signaling.
- An intracellular transporter that carries and delivers serotonin throughout synaptic vesicles.
- A transmembrane transporter that prevents hyperactivity overstimulation by re-uptaking serotonin from the synapse.
Therefore, suppose we compare this signaling pathway model to the analyzed experimental test. We can vividly acknowledge that TransA acts as a serotonin reuptake transporter since it is present in the plasma membrane of nerve cells and TransB is a serotonin vesicle transporter that is present and located in the cytoplasm. As a result, the majority of TransB is speculated to be present in synaptic vesicle membranes.
Answer:
D
Explanation:
It's d because it shows it in the middle of the circle arrow thing.
These are called synaptic vesicles
They are two electrons in a neutral atom of helium.
