Saturated fats make the membrane stiff because they are solid at room temperature, and unsaturated fats like fish oil, which are liquid at room temperature, make it bend which helps the cell work better.

Explain what effect more cholesterol in the plasma membrane will have on the membrane?
Increasing cholesterol in the plasma membrane can make the membrane more rigid and less fluid. This can affect membrane permeability and the function of membrane proteins. Additionally, high levels of cholesterol can lead to the formation of lipid rafts, which can impact cell signaling pathways.
What is a contrast line and how do you use it in your composition?
explain the use of line of composition?
What model is used to explain the componets and properties of plasma membrane?
The Fluid Mosaic Model is used to explain the components and properties of the plasma membrane. This model describes the plasma membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that can move and interact within the membrane.
Define and explain the difference between rigidity and fluidity?
Rigidity refers to inflexibility or stiffness, where there is limited ability to change or adapt. Fluidity, on the other hand, suggests flexibility and adaptability to changing circumstances or environments. In essence, rigidity connotes a more fixed state, while fluidity implies a more dynamic and responsive state.
Explain what thematic transformation is in a composition and give an example of its use in composition?
this never has the answers i need!
What were the problems associated with Davson and Damielli model of the cell membrane?
The Davson-Danielli model of the cell membrane proposed a lipid bilayer sandwiched between two layers of proteins, suggesting a simple, static structure. However, it failed to account for the fluidity of membranes and the presence of integral proteins that span the lipid bilayer. Additionally, the model did not explain the asymmetrical distribution of lipids and proteins, which is critical for membrane function. This led to its eventual replacement by the fluid mosaic model, which better represents the dynamic and complex nature of cell membranes.
Is the composition of air consistent Explain your thinking?
nothing
What is a model used to explain the components and properties of a plasma membrane?
The fluid mosaic model is commonly used to explain the structure and function of the plasma membrane. It describes the membrane as a fluid lipid bilayer with embedded proteins that can move laterally, giving the membrane its dynamic nature. The model helps illustrate how the plasma membrane controls the passage of substances into and out of the cell.
In what area have greek myths influenced your culture?
they have influenced our culture in the areas of agriculture.?
Explain the structure of the fluid mosaic model?
The cell membrane is made up of a variety of molecules including phospholipids, proteins, sugars, and other various building blocks. Fluid mosaic refers to the ability of these elements to shift about the cell membrane, which is ever-changing. Much of the ability to shift comes from the unsaturated lipid chains in the cell membrane, which have kinked structures that prevent the phospholipids of which they are a part from packing tightly together. The fluidity of the membrane is essential for some small molecule transfer between the inside and outside of a cell, as well as the activation of some important pathways which require molecules embedded within the cell membrane to either split or join.
What does chemistry seek to explain?
Chemistry explain the chemical composition and structure of materials, the interaction of substances and produce new materials.
What is cell membrane explain in urdu?
plasma membrane is the outer most boundary of animal cell.it is chemically composed of lipids and proteins.it is selectively permeable allow certain materials to move in and out.fluid mosaic modle explain its structure.
