Why do cells prefer to use carbohydrates as a source of energy before they use fats and proteins.

Semmy [17]2 years ago

The primary role of carbohydrates is to supply energy to all cells in the body. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Because the energy from glucose comes from the chemical bonds between the carbon atoms.

Answer:

Carbohydrates are primary sources of energy but fats and lipids are no primary sources of energy.

mote1985 [20]

The Molar concentration of your analyte solution is 1.17 m

<h3>What is titration reaction?</h3>
  • Titration is a chemical analysis procedure that determines the amount of a sample's ingredient by adding a precisely known amount of another substance to the measured sample, with which the desired constituent reacts in a specific, known proportion.

Make use of the titration formula.

The formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base.

if the titrant and analyte have a 1:1 mole ratio. (Molarity is a measure of a solution's concentration represented as the number of moles of solute per litre of solution.)

26 x 1.8 = 40 x M

M = 26 x1.8 /40

M = 1.17

The Molar concentration of your analyte solution is 1.17 m

The following reaction occurs in aqueous solution: NH4 + (aq) + NO2 - → N2 (g) + 2H2O (l) The data below is obtained at 25°C.
GREYUIT [131]

Answer: The order with respect to NH_4^+ is 1.

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

NH_4^++NO_2^-\rightarrow N_2+2H_2O

Rate=k[NH_4^+]^x[NO_2^-]^y

k= rate constant

x = order with respect to NH_4^+

y = order with respect to ANO_2^-

n = x+y = Total order

From trial 1: 3.2\times 10^{-3}=k[0.0100]^x[0.200]^y    (1)

From trial 2: 6.4\times 10^{-3}=k[0.0200]^x[0.200]^y    (2)

Dividing 2 by 1 :\frac{6.4\times 10^{-3}}{3.2\times 10^{-3}}=\frac{k[0.0100]^x[0.2000]^y}{k[0.0200]^x[0.200]^y}

2=2^x,2^1=2^x therefore x=  1

Thus order with respect to NH_4^+ is 1.

How are protons and neutrons similar? How are they different?
ad-work [718]

Consider the following reaction.Cr2O3(s) + 3CCl4(l) 2CrCl3(s) + 3COCl2(g). When the green solid is mixed with the colorless liq
Elena L [17]

Answer:

The answer to your question is: letter B

Explanation:

Reaction

                 Cr2O3(s)   +   3CCl4(l)   ⇒  2CrCl3(s)  +   3COCl2(g)

From the information given and the reaction, we can conclude that:

Green solid = Cr2O3 (s)     "s" means solid

Colorless liquid = CCl4 (l)    "l" means liquid   and is the other reactant

Purple solid = CrCl3(s)        CrCl3 is purple and "s" solid

Then, as a green specks remains it means that the excess reactant is Cr2O3, so, CCl4 is the limiting reactant.
