Large molecules such as hormones materials are expelled from cells during exocytosis
<u>Explanation:</u>
The materials inside the cells are transferred to the outside of the cell and this manner is termed as Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.
For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.
Different enzymes have specific active sites which can only catalyze one <span>substrate. Enzyme-substrate complexes are produced only when the substrate fits into the active site :)</span>
Answer:
A retrovirus is an RNA virus that is duplicated in a host cell using the reverse transcriptase enzyme to produce DNA from its RNA genome. The DNA is then incorporated into the host's genome by an integrase enzyme. The virus thereafter replicates as part of the host cell's DNA.
Convection currents are caused by the colliding of cold and warm air. At night, air above water is warm and air above land is cold. The opposite is true in daytime. When the warm air hits the cold air, which is more dense, it is pushed upward. Then it travels laterally until it cools. It comes back down and pushes up the former cold air, which is now warm. This repeats many times.
Answer:
Explanation:Complementary base pairing is important in DNA as it allows the base pairs to be arranged in the most energetically favourable way; it is essential in forming the helical structure of DNA. It is also important in replication as it allows semiconservative replication.
