How Neurotransmitter molecules are removed from a synapse by?
Neurotransmitter molecules are removed from a synapse through a process called reuptake or enzymatic degradation. In reuptake, the neurotransmitter is taken back up into the presynaptic neuron. In enzymatic degradation, special enzymes break down the neurotransmitter molecules into inactive byproducts.
How cell may vary the amount of enzyme?
Two main ways: synthesis and degradation. Each step in the process leading to synthesis of the enzyme can be regulated - gene expression, mRNA processing and stability, mRNA translation.
MRNA is eventually broken down by what enzyme?
mRNA is eventually broken down by ribonucleases, which are enzymes that catalyze the degradation of RNA molecules.
How are enzymes degraded?
Enzymes are degraded by proteolytic enzymes that break down the peptide bonds in the protein structure. This degradation can occur in lysosomes, which contain acidic hydrolases, or in the cytoplasm with the help of proteasomes. Enzyme degradation is important for regulating enzyme levels and activity in the cell.
What enzyme breaks down RNA?
RNase (ribonuclease) is an enzyme that breaks down RNA molecules by cleaving the phosphodiester bonds that link RNA nucleotides together. It is involved in various cellular processes such as RNA degradation, RNA processing, and RNA quality control.
What is the functiom of pepsinogen?
Pepsinogen is the precursor for Pepsin, an enzyme for the degradation of protein.

In enzymatic degradation, special enzymes break down the neurotransmitter molecules into inactive byproducts.
The activity of acetylcholine in a synapse is terminated by?
Its degradation by a hydrolytic enzyme on the postsynaptic membrane.
What is a degradation?
A degradation reaction breaks down a large molecule into smaller molecules. For example, the enzyme catalase breaks down Hydrogen Peroxide into Oxygen and Water.
Does Sertraline contain a MAO inhibitor?
No, Prozac (or fluoxetine) is a SSRI (selective serotonin reuptake inhibitor) and there is no effect on the monoamine oxidase enzyme.
How cell may vary the amount of enzyme?
Two main ways: synthesis and degradation. Each step in the process leading to synthesis of the enzyme can be regulated - gene expression, mRNA processing and stability, mRNA translation.
Is or are Protista digested By The Enzyme Protease?
No. The enzyme protease breaks or digests proteins into [the constituent] amino acids; so, typically, Protista has It's proteins well protected from Protease degradation.
Which enzyme converts fibrin to fibrin degradation products?
Plasmin, a serine protease, is the enzyme responsible for converting fibrin into fibrin degradation products. Plasmin is activated from plasminogen in the presence of tissue plasminogen activator (tPA) or urokinase.
What neurotransmitter does not go through the re-uptake process?
Acetylcholine is a neurotransmitter that does not go through the reuptake process. Instead, it is broken down by an enzyme called acetylcholinesterase in the synaptic cleft.
MRNA is eventually broken down by what enzyme?
mRNA is eventually broken down by ribonucleases, which are enzymes that catalyze the degradation of RNA molecules.

Enzyme degradation is important for regulating enzyme levels and activity in the cell.
What happens when enzyme reaches optimal temperature?
When an enzyme reaches its optimal temperature, its catalytic activity is at its maximum. The rate of enzymatic reactions increases, leading to faster conversion of substrates to products. However, if the temperature exceeds the optimal range, the enzyme can denature and lose its function.
