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

Lipids and proteins.

Lipids are macromolecules which provide insulation
. 
A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

Proteins are biological macromolecule and mostly composed of enzymes.<span> Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators. <span> </span></span>
