What else can I help you with?
What controls the movement in and out of the cell in plant cells?
cell membrane aka plasma membrane
What is the difference between cell surface membrane and plasma membrane?
The diffrence is that the cell membrane is just a barrier between the exterior enviroment and the interior of the cell, while the cell surface membrane exerts control over what enters/leaves the cell! :)
What is an example of water clinging to a plant?
An example of water clinging to a plant is when raindrops form on the surface of a leaf. This phenomenon occurs due to surface tension, which allows water molecules to adhere to the leaf's surface. Additionally, this can be observed in dew droplets that accumulate on grass in the early morning, showcasing water's ability to cling to various plant surfaces.
What protein that projects from the outer surface of the membrane is termed?
The protein that projects from the outer surface of the membrane is termed as an extrinsic or peripheral membrane protein. These proteins are not embedded within the lipid bilayer but instead are attached to the surface of the membrane.
What breaks down fats into globules?
Bile salts produced by the liver break down fats into smaller globules in the small intestine. This process, called emulsification, increases the surface area of fats, making it easier for enzymes to break them down further into individual fatty acids for absorption.

The [mucosal] Pleural membrane.

When liquid is added to a solution of a detergent in water the detergent breaks up large globules of the lipid into much smaller globues what effect do you think a detergent would up large globules o?
Adding a detergent to a solution with large globules of lipids helps break them down into smaller globules due to the detergent's ability to lower surface tension. This allows the lipids to disperse more evenly in the solution, improving their solubility and making it easier to wash away dirt and grime from surfaces.
What is the name of a surface membrane molecule that causes an immune reaction?
Antigens are surface membrane molecules that cause an immune reaction.
Does the cristae increase or decrease the surface area of the inner membrane?
Cristae increases the surface area of the interior membrane of the mitocondria.
What is the characteristic of the lipase enzymes?
Lipases perform a process called emulsification which breaks fat globules into smaller particles. This gives more surface area for the enzymes to then break the oils into fatty acids.
What are folds of the cell membrane on the free surface?
The folds on the free surface of a cell membrane are called microvilli. They increase the surface area of the cell membrane, allowing for greater absorption of nutrients and molecules. Microvilli are commonly found in cells that are involved in absorption, such as in the lining of the small intestine.
What is the coversion of fat globules into smaller droplets?
The conversion of fat globules into smaller droplets is known as emulsification. This process involves the mechanical agitation or mixing of fat globules in the presence of an emulsifying agent, which stabilizes the smaller droplets and prevents them from coalescing. Emulsification is crucial in various food preparations and in the digestion of fats, as it increases the surface area for enzymes to act upon, facilitating better fat absorption.
