The plasma membrane has a double layer of phospholipids with proteins dispersed throughout. These proteins help increase the durability of the membrane, as well as help with filtration.

Answer:
1000 mM
Explanation:
Using V = -60 mV㏒₁₀[K/K'] where V = membrane potential = -60 mV, K = intracellular concentration = unknown and K' = extracellular concentration = 100 mM
So, V = -60 mV㏒₁₀[K/K']
-60 mV = -60 mV㏒₁₀[K/K']
dividing both sides by -60mV, we have
-60 mV/-60 mV = ㏒₁₀[K/K']
㏒₁₀[K/K'] = 1
taking antilogarithm of both sides, we have
[K/K'] = 10¹
multiplying both sides by K', we have
K = 10K'
K = 10 × 100 mM
K = 1000 mM
So, the intracellular Cl- concentration is 1000 mM

Answer No 1:
Phospholipids are made up of phosphorus head and two fatty acid molecules. These phosphorus head and fatty acid tail is joined together by glycerol. Fatty acid molecules are made up of Carbon, hydrogen and oxyge. Hence,carbon and hydrogen can be said as two other elements present in phospholipids.
Answer No 2:
The building blocks of lipids are glycerol and fatty acids.
Lipids can be described as vital organic molecules which are not soluble in water. They are made up of chains of carbon, hydrogen and oxygen. Someof the examples of lipids are fats and oils. Lipids are the main molecules present in an organisms cell membrane and hence have huge biological importance.
Answer No 3:
Lipids are biologically important molecules as they play very vital roles in the functioning of an organisms body. Two of the functions of lipids are:
- Lipids and phosphorus molecules combine to form phospholipids. The phospholipids are the main molecules out of which the cell membrane is made. Hence, lipids play an essential role in providing the cell membrane its structure.
- Lipids store energy and provide insulation to the body of an organism.
