Enzymes are catalysts that can be used more than once. If a substance needs to get broken down then it can use the corresponding enzyme to attach itself and break it down into simpler substances. After this is gone, the next substance might come up and attach itself to the enzyme like a lock-and-key model.

Therefore the answer is A) Enzymes accelerate chemical reactions without getting used up in the process.

Tems11 [23]

Answer: The correct answer is A. During this time, cells take in nutrients, which are important for energy, growth, and repair of the cell.

Interphase is the first phase of the cell cycle. During this phase, the cell takes in nutrients, which are important for energy, growth, and repair of the cell.  

In other words, cell prepares for division by growth, synthesizing essential proteins, and duplicating the DNA. This phase occurs prior to cell division.

This phase is primarily divided into G1, S, and G2 phase. G1 and G2 are the gap phases during which cellular growth and synthesis of essential proteins take place.

S phase ( synthesis phase) includes the duplication of the DNA so two identical cells are obtained after cell division.

Thus, the correct statement, which describes the interphase is A.

Food and bloodstains on clothes may contain proteins and fats. Explain how enzymes in biological washing powders act to remove f
Triss [41]

Explanation:

Enzymes would break down the protein and fat molecules when washed as some enzymes are designed to work in that type of atmosphere. Additionally, enzymes are also known as biological catalysts which means they speed up chemical reactions which are taking place. Hence, they help break down molecules that may be in food and in fats.

Hope this helps :)
