Answer:
The correct option is D.
Explanation:
Protein generally are very sensitive macro molecules; they have specific temperatures and pH that are ideal for their operations, this is especially true for proteins that act as enzymes in biochemical reactions.
There are four different types of structures that a protein can assume, these are primary, secondary, tertiary and Quaternary structure. The structure of a protein determines the kind of function it can perform.
There are some factors that can destroy the structure and functions of proteins, these include excessive heat and pH. A protein is said to be denatured when its secondary and tertiary structure have been disrupted or destroyed. Denaturation does not affect the primary structure of the protein, thus, the peptide bond remains intact.
Denaturation is usually temporary and can be reversed if the factors that cause denaturation is removed, this process is called RENATURATION. Renaturation process allow the protein to refold and resume its functions. But sometimes, denaturation can be permanent and irreversible leading to permanent loss of protein functions.
Answer:
Eukariotic cells are bigger and complex than bacteria. The difference between cystoskeleton of eukariotic and bacteria cells is the type of proetein in each one.
Explanation:
The cytoskeleton is composed mainly in arrays of protein filaments. Its function is to maintain the shape of the cell, maintain in place the organelles (such as mitochondria, nucleus, etc.) and the transport throughout the cell. Every cell has a cytoskeleton, eukaryotic, bacteria and archaea. Eukaryotic cells are bigger than bacteria and have more organelles in them to maintain in place, this is why cytoskeleton are bigger and complex. The bacteria are a single cell, simpler, with a few organelles, the cytoskeleton is more simple but important. The cytoskeleton is similar in both, the difference is the type of proteins in them. In bacteria are simple proteins, meanwhile, in eukaryotic are a complex protein.
Answer:
Option 4
Explanation:
Folate is vitamin B and occurs naturally in various food items such as green leafy vegetable, lentils, peas, beans, in fruits such as banana, melon, and enriched products such as bread, juices etc. Folate is essential for making up genetic material or DNA. Out of all given options, option 4 has both lentil and spinach (green leaves) which are rich source of folate. Option 1 has bread as a source of folate. Hence, the correct answer is option 4.
