Some retroviruses may utilize a special enzyme known as reverse transcriptase, which a RNA virus can use to make DNA using the RNA as a template.

What play many key roles in the manufacture of proteins?
RNA .
The key enzyme involved in carbon fixation is called?
rubisco!
Although it is too simple an explanation the concept of a key fitting into a lock is descriptive of the?
matching of enzyme with the substrate
What fits with an enzyme to make a reaction occur?
The substrate fits into the enzyme, much the way a key fits in a lock. Sometimes there are other "modulators" that also fit in the enzyme.
Explain why a certain virus will attach to only one or few types of cells?
Virus attachment is dependent upon the cell surface receptor that can interact with the protein on the virus surface. The interaction is akin to a lock and a key. The key is the protein on the virus, and the lock is the cell surface receptor. A key will only get into the correct lock.

RNA .
What effect does the lock and key process have on the enzyme structure?
Easily Explained thusly: When the key is in the lock the Enzyme has one Structure, and when the key is not in the lock the Enzyme has another Structure. Note that the presence of a key may either activate or deactivate an Enzyme, depending upon the conditions.
What is the key enzyme in nitrogen fixation?
nitrogenase
In the lock and key method which is the lock?
The Key is the substrate while the key is the enzyme. Just finished learning this :)
What is the key enzyme in digestion of polysaccharides?
alpha-amylase
What is considered a model for enzyme?
the answer is lock and key model .
Why are virus's protein important?
They form the capsid that encloses the genetic material and retroviruses contain the protein enzyme reverse transcriptase. Also the proteins, especial glycoproteins, are the key that enters the lock of a cells protein markers.

How is a substrate and its enzyme like a lock and key?
An enzyme is shaped so that a specific substrate can attatch to it. A lock and a key function in a similar way. Each lock is shaped so that only a certain key can open it.
What enzyme speeds up a chemical reaction is known as?
All enzyme's are catalysts for certain chemical reactions. Each enzyme will only work with a certain substrate one analogy being that the enzyme is a key and the substrate is a keyhole, and each enzyme has a unique enzyme.
The key enzyme involved in carbon fixation is called?
rubisco!
What is the difference between the lock and key model versus the induced fit model of the enzyme substrate complex?
The lock and key model means that the substrate must perfectly fit the enzyme, and the enzyme does not change. The induced fit model is different as when the substrate fits together with the enzyme, the enzyme itself will change to either join substrates together or break a substrate down.
