The enthal difference between the reactants and the products is equal to the amount of energy released to the surroundings. ... A reaction in which energy is absorbed from the surroundings is called an endothermic reaction. In endothermic reactions the enthalpy of the products is greater than the enthalpy of the reactants.

When vesicles of the cardiac sarcoplasmic reticulum (CSR) are incubated with ATP Mg^2+ and Ca^2+, they take up Ca^2+ and reach a
abruzzese [7]

Answer

I added 4 and 5 as an attachment due to time constraint.

Explanation:

1. at a steady state ca2+ taken by vesicle = 40n/mol

enclosed volume of CSR = 5μ/mg

concentration of ca2+ in vesicle =

40*10⁻⁶/5x10⁻⁶

= 0.008

= 8x10⁻⁹mol/L

2. radius of circle =75nM

volume = 150nm

volume of vesicle = 4/3 x pi x r³

= 1.33 x 3.14 x (75x10⁻⁹)³

= 1.77 x 10⁻²¹

when we convert this we get

1.77x10⁻¹⁸L since 1m³ is equal to 100oL

surface area =4x3.14x(75x10⁻⁹)²

= 12.56x5.625⁻¹⁵

= 7.065x10⁻¹⁴m²

this is 7.065x10⁻¹⁰cm²

3. number of vesicle/CSR

= 5x10⁻⁶/1.77x10⁻¹⁸

= 2.824x10¹²

surface are = 2.824x10¹² x7.06x10⁻¹⁰

= 19.95x10²
