B)
produce heat energy
C)
reduce the activation energy of a reaction
D)
take energy from cellular work
Answer:
A) provide energy for cellular work
Explanation:
The Adenosine triphosphate (ATP) molecule is the nucleotide known in biochemistry as the "molecular currency" of intracellular energy transfer; that is, ATP is able to store and transport chemical energy within cells. ATP also plays an important role in the synthesis of nucleic acids.
ATP always GIVES ENERGY
The primary function of ATP is to provide energy for cellular work. It does so by transferring a phosphate group to a molecule and forming ADP. This key process drives cellular metabolism and enables life-critical activities.
The key role of ATP, also known as Adenosine Triphosphate, is to provide energy for cellular work. ATP carries out this function by transferring a phosphate group to a molecule. This breaks a high energy bond and forms ADP (Adenosine Diphosphate), releasing energy that can be utilized by the cell to do work.
ATP acts as the primary energy currency of the cell. This process is at the heart of cellular metabolism and is common to all living organisms. Essentially, ATP acts as a bridge, transferring energy from chemical reactions that yield energy to cellular processes that consume energy, such as muscular contraction, cell division, or the synthesis of biomolecules.

The ratio of Al^3+ ions to S^2- ions in a neutral compound is 2:3.
The neutral compound formed by aluminum ion and sulphide ion is aluminium sulphide, with chemical formula Al2S3. Looking at the chemical equation, you will observe that, for each molecule of aluminium sulphide, there is two atoms of aluminium and three atoms of sulphur. This is the ratio of combination for the compound, that is, for every two atoms of aluminium, there are three atoms of sulphur, thus, the combination ratio is 2:3.
The density of Argon gas at a pressure of 753 mmHg and a temperature of 35 °C is equal to 1.59 g/L.
The state of a quantity of gas is calculated by its pressure, volume, and temperature. The ideal gas law can be explained as the product of the volume and pressure of gas is equal to the multiplication of the universal gas constant and absolute temperature.
The mathematical equation for an ideal gas can be written as follows:
PV = nRT
PV =(m/M) RT
PM/RT = m/V
d = PM/RT
Where n is the moles of gas, T is the temperature of the gas, V is the volume of the gas, and R is the gas constant.
Given, the temperature of argon gas, T = 35 °C = 35 +273 = 308 K
The pressure of the argon gas, P = 753 mmHg = 1.01 atm
The molar mass of the Argon gas, M = 40 g/mol
Substitute V, R, P, and T in the ideal gas equation, we get:
The density of Argon gas, d = PM/RT
d= 1.01 ×40/(0.082 × 308)
d = 1.59 g/L
Therefore, the density of Ar gas is 1.59 g/L.
