Answer:
Explanation:
An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.
Enzymes are produced naturally in the body.
For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.
Answer:
b. unable to terminate transcription of some genes.
Explanation:
Rho protein is a polypeptide with 419 residues and is found in prokaryotic cells such as bacteria.
Termination refers to the point where a signal is made for transcription to stop. This usually occurs when a part of the DNA known as the terminator is transcribed. The transcription of this part halts then transcription process.
A lack of the rho protein means transcription of some genes won’t be able to be stopped( terminated).
