1.what are three factors that affect the rate of chemical reactions?

Lunna [17]

Explanation:

The factors that affects the rate of chemical reactions are;

Nature of reactants
Concentration of reactants or pressure
Temperature
Presence of catalyst
Sunlight

In our body, the nature of reactants is very important. A food substance in solid form undergoes slow digestive process because it has little surface area exposure for the action of digestive chemicals. Most solid food are usually chewed in the mouth before digesting them to increase their surface area.

The increasing order of food digestion is;

lumps to granules to powder and to liquids.

Need a hypothesis for “How are proteins built from RNA”

Dima020 [189]

Hi!

Hypothesis:

<em>Proteins are built from the translation of messenger RNA (mRNA) molecules</em>

RNA, or ribonucleic acid, is a structure that is similar to DNA, except that it exists as a single strand, consists of a ribose sugar instead of a deoxyribose sugar and has the base uracil (U) instead of thyamine (T).

RNA is generated through transcription of the DNA molecule, resulting in a <em>complementary </em>molecule of the template DNA strand. For instance, if the sequence of the DNA was:

ATGCGCAGTTATTGCGAT

The corresponding RNA sequence will be:

UACGCGUCAAUAACGCUA <em>(complementary with U instead of T)</em>

<h3><u>From RNA to Protein</u></h3>

The RNA molecule in our case is known as the mRNA. After transcription the mRNA molecule is transported to the cytoplasm, where a ribosome binds to it for another molecule to translate the sequence. This translation is mediated by an RNA molecule known as the tRNA molecule which enters the ribosome to catalyze the reaction.

These molecules identify a sequence of 3 bases (codon) and for specific codon sequences, the tRNA allocates specific amino acid. For instance, for the codon <em>UCA</em>, the tRNA will allocate a <em>Serine residue.</em>

This translation process starts at specific three base sequences, known as start codons, and terminates at specific three base sequences known as stop codons.

In this manner, a sequence of amino acids respective to the mRNA codon sequence is synthesized, and as we identify proteins as chains of amino acids that are covalently linked together through peptide bonds, we can clearly see that proteins are built directly from RNA, and indirectly from DNA.

Hope this helps!

What is electrolyte balance in the body?

Vlad1618 [11]

The electrolytes present in our body should be in the right concentration. This is said to be electrolyte balance.

Why does an electrolyte imbalance occur?

Electrolyte imbalance is caused when the body fluids are present in large amount. When we sweat or vomit more, it can be due to the lower level of some electrolytes. So, it is necessary that the electrolytes should be in proper proportion.

Electrolytes plays a very important role in our body. It helps in regulation of fluids present in blood and blood plasma, normalizes the pH of blood, allows the contraction of muscles and so on. For all these necessary roles to occur, our electrolytes should be in proper concentration. This is called electrolyte balance.
