In membrane proteins, fluidity is increased by
increase in cholesterol content
higher percentage of unsaturated fatty acids
decrease in temperature
integral proteins
The correct answer is "higher percentage of unsaturated fatty acids".
Fluidity of membrane increases with increase in temperature, increase in unsaturated fatty acids.
Cholesterol content acts as buffer for membrane fluidity since at low temperatures, the fluidity will increase and at high temperatures, the fluidity will decrease.
In membrane proteins, fluidity is increased by increase in cholesterol content higher percentage of unsaturated fatty...

A high ratio of saturated to unsaturated fatty acids in a membrane results in a/an 1.) more kinks in the membrane structure 2.) increased fluidity in the membrane structure 3.) decreased rigidity in the membrane structure 4.) increased rigidity in the membrane structure which of the following is NOT a product of Krebs cycle 1.) NAD+ 2.) ATP 3.) FADH2 4.) CO2 Most proteins interact with DNA in the form of 1.) head to head or tail to tail homodimers...
An increased amount of unsaturated fatty acids in cytoplasmic membranes is a molecular adaption of_ since_ thermophiles, unsaturated fatty acids help the membrane remain in a solid state at high temperatures to block excessive transport activity. psychrophiles, unsaturated fatty acids help the membrane solidify at lower temperatures at block transport activity. thermophiles, unsaturated fatty acids help the membrane remain in a semifluid state at high temperatures to help carry out transport and bionergetic functions. O psychrophiles, unsaturated fatty acids help...
3. Many membrane process such as transport or signal transduction depends on the fluidity of lipids membrane. How fatty acids and cholesterol effect the fluidity of the membrane.
3. Many membrane process such as transport or signal transduction depends on the fluidity of lips membrane. How fatty acids and cholesterol effect the fluidity of the membrane.
Membrane fluidity for bacteria is critical. What type of fatty acids would you expect bacteria to synthesize as growth temperature increases? Why type of fatty acids would you expect bacteria to synthesize as growth temperature decreases? Why cannot bacteria simply synthesize the same type of fatty acids regardless of temperature?
membrane fluidity? The presence of phospholipids with increased number of double bonds will increase decrease have no effect on
Fatty acids are anabolized by a process called 1.) fatty acid synthesis 2.) gluconeogenesis 3.) beta oxidation 4.) glycogen storage Most proteins interact with DNA in the form of 1.) head to head heterodimers 2.) head to tail homodimers 3.) head to tail heterodimers 4.) head to head or tail to tail homodimers Which of the following is NOT a product of Krebs cycle 1.) NAD+ 2.)ATP 3.) FADH2 4.) CO2 A high ratio of saturated to unsaturated fatty acids...
LIPID AND MEMBRANE QUESTIONS 1. If an unsaturated fatty acid has 18 carbons, a double bond at position would be in notation - 2. The functional groups which hold fatty acid molecules and glycerol molecules together in triacylglecerol molecules are called: 3. If a triacylglycerol is heated in aqueous sodium hydroxide (lye) solution glycerol and the sodium salts of fatty acids are produced. This mixture of sodium salts of fatty acids is called in common terminology 4. Name the four...
How are lipid bilayers formed? What is their fluidity dependent on? Group of answer choices: - Hydrophobic interactions are the driving force of forming bimolecular sheets of lipids spontaneously. Due to the hydrophobic effect, any tears in the lipid bilayer cause it to spontaneously rearrange to eliminate the free edge. Membrane fluidity depends on the percentage of unsaturated fatty acids. - Hydrophobic interactions are the driving force of forming bimolecular sheets of lipids spontaneously. Due to the hydrophobic effect, any...
