What else can I help you with?
What can you conclude about the cell membrane structure if liquid soluble molecules move across the membrane?
It can be concluded that if the liquid soluble molecules move more readily across the membrane then the membrane must be made of lipids. When two parts are made of similar material then they will be more likely to allow other particles like them to pass.
What happen during the facilitated diffusion?
Facilitated diffusion occurs against the osmotic potential/concentration gradient and requires energy at the expense of the ATP hydrolysis. There are several way in which this diffusion could occur in the cells. The first one being the ion exchangers. The ion exchangers are coupled with ATPase activity and they exchange ion(s) across the membrane. The most classical example of ion exchanger is the Na+/K+ ion exchanger and Ca+ ATPase. Other way of the facilitated diffusion in the ion channel. These could be voltage gated channel that open in response to the change in the membrane potential and the other being ligand gated channel that operate under the effect of ligand binding.
What would happen if a cell membrane became hard?
If you mean as this as impenetrable, no water or waste could come in or out. The cell would then be a non living object, or a 'dead cell'. Do you mean hard as in solid? because if it was solid, you would not be alive.
Where does the exchange of materials between a cell and its environment take place?
a cell membrane
How do carrier proteins help substances enter the cell?
Carrier proteins facilitate the movement of substances across the cell membrane by binding to specific molecules and transporting them through the membrane. This process is known as facilitated diffusion and helps substances enter cells by bypassing the lipid bilayer barrier.
What would happen if materials could not move across the cell membrane?
If materials could not move across the cell membrane, essential nutrients and molecules needed for cell function would not be able to enter the cell, leading to cell dysfunction and potential cell death. Waste products and toxins would also not be able to leave the cell, causing toxic buildup and further disrupting cellular processes.
What would happen to a cell if materials could not move across the cell membranes?
it will died
What happen to a cell if materials could not move acrss the cell membrane?
this was in the science textbook and it was a challenge question so use your noggin and dont rely on others to use yours for you
What will happen if a partially permiable membrane is replaced with a non permiable membrane?
If a partially permeable membrane is replaced with a non-permeable membrane, no substances will be able to pass through the membrane. This will prevent the movement of molecules across the membrane and alter the osmotic balance between the two sides of the membrane. This could lead to changes in cell volume and affect cellular processes that rely on osmotic balance.
What is this method of molecular transport is called?
Molecular Transport (in cells) is the movement of materials across a cell membrane. The two kinds of Molecular Transport used in organisms are Active Transport and Passive Transport. Active Transport- materials move across the plasma membrane with the use of energy (like Adenosine Triphosphate) Passive Transport- materials move accross the plasma membrane without the use of energy
What would happen if a membrane protein we're unable to bind to a signaling molecule?
If a membrane protein is unable to bind to a signaling molecule, it may not be able to transmit the intended signal across the cell membrane. This could result in disrupted cellular communication and potentially lead to improper cell function or response to stimuli.
What about a cell's resting membrane potential is FALSE?
A false statement about a cell's resting membrane potential could be that it does not involve the movement of ions across the cell membrane. In reality, the resting membrane potential is primarily due to the unequal distribution of ions, such as sodium and potassium, across the membrane, maintained by ion channels and pumps.
What is the organelle allows nutrients and other materials to enter and leave the cell?
cell membrane
What can you conclude about the cell membrane structure if liquid soluble molecules move across the membrane?
It can be concluded that if the liquid soluble molecules move more readily across the membrane then the membrane must be made of lipids. When two parts are made of similar material then they will be more likely to allow other particles like them to pass.
What would happen to the size of the cell membrane if a cell were to undergo a lot of endocytosis and no xocytosis?
If a cell undergoes a significant amount of endocytosis without compensatory exocytosis, the overall size of the cell membrane would decrease. Endocytosis involves the invagination of the membrane to engulf materials, leading to the internalization of membrane components, which reduces the surface area of the membrane. Over time, this imbalance could potentially lead to a decrease in cell size or disrupt normal cellular functions due to altered membrane dynamics.
What would happen if molecules could not pass through the cell membrane?
Murder, in the first degree...jk
What would happen is the fatty acids in a cell membrane were polar molecules?
If the fatty acids in a cell membrane were polar molecules, the overall structure of the membrane would be compromised. Polar fatty acids would lead to increased interactions with water, disrupting the bilayer arrangement essential for membrane integrity. This change could hinder the membrane's ability to act as a barrier, impairing cellular function and potentially leading to cell lysis or dysfunction. Additionally, the membrane's fluidity and permeability properties would be altered, affecting the transport of molecules across the membrane.
