Answer:
- Numerous amino acids <u>allow for proteins to perform many diverse functions in organisms</u>.
- The branching structure of some carbohydrates <u>maximize the amount of glucose available for quick energy</u>.
Explanation:
Amino acids are the <u>building blocks</u> of proteins. In humans, <u>all forms of proteins</u> are made up of <u>20 different types of amino acids</u>. The <u>sequence of amino acids</u> is the key to the production of <u>specific proteins</u>. If the sequence is changed, the target protein will be changed. So, only 20 types of amino acids can produce millions of proteins through different combinations. For example, for a protein with 4 amino acids sequence, 160,000 types of polypeptide chains can be formed (20 X 20 X 20 X 20). Since we know that proteins are key players in cell functioning, their multiple combinations lead to diverse functions in the organisms.
Carbohydrates are an <u>excellent source of energy</u>. Although branching decreases the water solubility of carbohydrates, it <u>compacts the energy-yielding monomers</u> in a <u>small space</u> so that they can be <u>stored</u> and, during starvation, they can produce an <u>extensive amount of energy</u> for long term survival. Carbohydrates in <u>animal and plant</u> bodies are stored as branched structures of <u>glycogen and starch</u>, respectively.

Answer:
Chemical properties are very useful in identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance.

HERE IS YOUR ANSWER
it is CHLOROPLAST which is only found in plant cell
HOPE THE ANSWER WILL HELP U!!!!!!! :-) :-) :-) :-)
<span> They are unable to pass through the plasma membrane and have different methods of action. They attach to their receptors in the target cell surface and influence activity within the cell through cytoplasmic intermediates called second messengers. </span>
<span>The two most important messengers are cAMP and inositol triphosphate. </span>
<span>Cyclic AMP: ATP is converted into cAMP after a series of reactions on the plasma membrane following the attachment of the hormone to the membrane. cAMP relays the signal from the membrane to the metabolic machinery of the cytoplasm. </span>
<span>Inositol Triphosphate: Involves the use of Ca+2 that regulates cellular protein activity.
