In the plasma membrane, _____ form(s) the lipid bilayer, __________determine(s) the fluid nature of the membrane, and __________
mainly determine(s) the function of the membrane.

a. phospholipids, cholesterol, proteins
b. phospholipids, proteins, cholesterol
c proteins, cholesterol, phospholipids
d. cholesterol, phospholipids, proteins
c. cholesterol, proteins, phospholipids

Expert Solution & Answer

Summary Introduction

Introduction:

The proteins are made of amino acids. The amino acids are of 20 types that combine in a varied manner to form proteins. The amino acids join together by peptide bonds. Proteins act as major substrates and reactants for the metabolic pathways. All the enzymes in the body that are crucial for the biochemical reactions are proteins.

Answer to Problem 1RAC

The correct answer is option (a) phospholipids, cholesterol, proteins.

Explanation of Solution

Explanation/justification for the correct answer:

Option (a) phospholipids, cholesterol, proteins. The phospholipids form the bilayer of the cell membrane, and the cholesterol promotes fluidity of the membrane to allow the movement of cytoplasm inside and the protein play a different role in the function of the cell membrane. So, the correct answer is option (a).

Explanation for incorrect answer:

Option (b) phospholipids, proteins, cholesterol. Phospholipids make up the lipid bilayer, and the cholesterol promotes fluidity to steroid and alcohol in its structure, and so it does not provide the function to the membrane. So, this is an incorrect option.

Option (c) proteins, cholesterol, phospholipids. The phospholipids form the bilayer that is integrated with proteins and protein do not form the bilayer of the plasma membrane. So, this is an incorrect answer.

Option (d) cholesterol, phospholipids, and proteins. Cholesterol does not make the bilayer; the bilayer is made up of phospholipids and embedded proteins. So, this is an incorrect answer.

Option (e) cholesterol, proteins, phospholipids. Phospholipids only make up the structure of the cellular membrane and do not determine the function of the membrane; this function is carried out by protein that is intrinsic and extrinsic. So, this is an incorrect answer.

Conclusion

Phospholipids form the bilayer which is made up of two lipid layers making a sandwich with protein embedded in between two layers; cholesterol provides fluidity and proteins help to determine the function of the membrane. Hence, the correct answer is option (a) phospholipids, cholesterol, proteins.

Students have asked these similar questions

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
