Calcium ions that act as second messengers are stored in _____.
bagirrra123 [75]

Answer:

Endoplasmic reticulum.

Explanation:

Second messengers are known as intracellular signaling molecules released from the cell in response to exposure to extracellular signaling molecules. Second messenger activate physiological changes at a cellular level, for example proliferation, migration, differentiation, survival, and apoptosis.

Calcium ions are hydrophilic, water-soluble molecules. They are present in intracellular component know as endoplasmic reticulum and quickly released when needed. They are necessary for many important functions including fertilization, muscle contractions, and neurotransmitter release.

Monosodium glutamate (NaC5H8NO4) is used extensively as a flavor enhancer what is its percent composition
torisob [31]

Answer:

% sodium= 13.6 % sodium

% carbon= 35.5 % carbon

% hydrogen= 4.7% hydrogen

% nitrogen = 8.3% nitrogen

% oxygen = 37.8 % oxygen

Explanation:

To find its percent composition means that we are to find to find the percentage of each of the constituents of the compound present.

The molar mass of monosodium glutamate is 169.11 gmol-1

Hence;

Percent of sodium= 23 gmol-1/169.11 gmol-1 × 100 = 13.6 % sodium

Percent of Carbon= 60 gmol-1/169.11 gmol-1 ×100 = 35.5 % carbon

Percent of hydrogen= 8/169.11 gmol-1 ×100 = 4.7% hydrogen

Percent nitrogen = 14/169.11 gmol-1 × 100 = 8.3% nitrogen

Percent oxygen = 64/169.11 gmol-1 ×100 = 37.8 % oxygen

What method would you use to separate sand from gasoline?
WARRIOR [948]

Answer:

Filtration (The process of separating liquids and solids)

Explanation:

Filtration works best when the solute isn't dissolved in the solvent. Basically like how you can filter dirt or sand from water. The opposite of this would be if water and sugar where mixed together you cannot unmix this duo with filtration but with the example given you can use the process of filtration to rid the gasoline of sand.

In a favorable reaction, the free energy of the products is ________ the free energy of the reactants. In a favorable reaction,
steposvetlana [31]

Answer:

In a favorable reaction, the free energy of the products is less than the free energy of the reactants.

Explanation:

The free energy of a system is the amount of a system's internal energy that is available to perform work. The different forms of free energy include Gibbs free energy and Helmholtz free energy.

In a system at constant temperature and pressure, the energy that can be converted into work or the amount of usable energy in that system is known as Gibbs free energy. In a system at constant temperature and volume, the energy that can be converted into work is known as Helmholtz free energy.

The change in free energy of a system is the maximum usable energy that is released or absorbed by a system when it goes from the initial state (i.e., all reactants) to the final state (i.e., all products).

In a chemical reaction, some bonds in the reactants are broken by absorbing energy and new bonds are formed in the products by releasing energy. As the reaction proceeds, the free energy of reactants is much greater than the products. As the products are formed, the concentration of reactants decreases and the difference in their free energy also decreases. This chemical reaction will occur until chemical equilibrium is achieved i.e., the free energy of the products and reactants is equal and the difference in their free energy is zero.
