Answer:
Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. Like all catalysts, enzymes take part in the reaction - that is how they provide an alternative reaction pathway.
Explanation:
<u>The major </u><u>difference</u><u> between bacterial chromosomes and eukaryotic chromosomes is </u><u>Bacteria </u><u>have a single circular </u><u>chromosome </u><u>whereas eukaryotes have several linear chromosomes.</u>
What is a bacterial chromosome called?
Bacterial chromosome is called nucleoid. It is an irregularly shaped and contains genetic material. It is also called as genophore.
What is meant by eukaryotic chromosome?
- Eukaryotic chromosomes are found in the cell's nucleus.
- The DNA inside the nucleus is organized into chromosomes. At the most basic level, a chromosome is a molecule of DNA that is tightly coiled around proteins called histones.
What is the difference between bacterial and human chromosome?
- Bacterial chromosomes are circular in contrast to human chromosomes, which are linear.
- Furthermore, bacterial circular chromosomes are found in the nucleoid area rather than the nucleus, an organelle that is membrane-bound.

<span>Chemical bonds hold atoms
together to form compounds. The answer is letter D. Chemical bonds may result
through the sharing of electrons as in covalent bonds or from the electrostatic
force of attraction between atoms with opposite charges as in ionic bond. There
are other bonds that exist to other compounds such as metallic bond and
hydrogen bonding. Also, the type of bonding will help us determine what will be
the phase of the compound. Just like in liquids, attractive forces are caused by
van der Waals bonds.</span>
Absolutely. If even a single cell cannot maintain homeostasts, how will it survive?
