What else can I help you with?
Molecules can pass through the cell membrane of the human cell?
Yes, molecules can pass through the cell membrane of human cells through various mechanisms such as simple diffusion, facilitated diffusion, or active transport. The size, polarity, and concentration gradient of the molecule influence how it crosses the cell membrane.
Osmosis occurs as water can cross the lipid bilayer through what?
Osmosis occurs as water crosses the lipid bilayer through aquaporin channels, which are membrane proteins specialized for water transport. These channels facilitate the movement of water molecules in and out of the cell, maintaining osmotic balance.
How does Oxygen cross cell membrane?
Oxygen and water molecules can penetrate the cell membrane due to small gaps that are created by the lipid molecules. Lipid molecules overlap each other which makes the gaps. The oxygen and water molecules then enter in the gaps. The cell membrane in this case is semi permeable.
What type of protein helps molecules not lipid soluble or too large pass through the cell membrane?
These proteins are attached to the membrane and their is a great variety of them. There one called the integral protein that crosses all the way through while others are triggered by biochemical reactions.These are also called carrior proteins and protein channels
Glucose molecules cross the cell membrane by means of?
The answer is that glucose crosses a semi-permiable membrane by the process of facilitated diffusion. It cannot be by osmosis, because osmosis is the moving of only water from a concentration of high to low.
What molecule crosses the plasma membrane by diffusion?
water
What molecule crosses the mitochondrial membrane?
Adenosine triphosphate (ATP) crosses the mitochondrial membrane to provide energy for cellular processes.
Molecules can pass through the cell membrane of the human cell?
Yes, molecules can pass through the cell membrane of human cells through various mechanisms such as simple diffusion, facilitated diffusion, or active transport. The size, polarity, and concentration gradient of the molecule influence how it crosses the cell membrane.
The concentration of a sugar is high inside a cell and sightly lower outside the cell What is most likley to occur if the sugar molecule can cross the membrabe?
When sugar molecule crosses the membrane the sugar molecule moves to the outside of the membrane. This is taught in science.
A lipid base molecule primarily composed of 4 interlocking rings of carbon that readily crosses a plasma membrane is?
testosterone
What molecule crosses a cell membrane more often than any other substance?
Water molecules cross a cell membrane more frequently than any other substance because of their small size and ability to move freely through the lipid bilayer. This process, called osmosis, allows water to maintain proper hydration levels inside the cell.
What substance is correctly paired to the way it crosses the plasma membrane?
Water crosses via osmosis. glucose via diffusion. Carbon dioxide needs assistance to pass through the membrane so it requires active transport.
What crosses lipid bilayers the slowest?
Large polar molecules and ions generally cross lipid bilayers the slowest due to their size and charge, which hinders their ability to move through the hydrophobic interior of the membrane. Additionally, molecules that are not lipid soluble or do not have specific transporters in the membrane will also have difficulty crossing the lipid bilayer.
Osmosis occurs as water can cross the lipid bilayer through what?
Osmosis occurs as water crosses the lipid bilayer through aquaporin channels, which are membrane proteins specialized for water transport. These channels facilitate the movement of water molecules in and out of the cell, maintaining osmotic balance.
How does oxygen crosses the plasma membrane if thr concentration of oxygen is lower inside the cell than it is outside the cell?
Oxygen crosses the plasma membrane through passive diffusion, moving from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell). This process occurs due to the concentration gradient and the lipid nature of the plasma membrane, which allows small, nonpolar molecules like oxygen to pass through easily.
What substances will cross the cell membrane through osmosis?
Only water is transported through the process of osmosis.
What substance crosses the cell membrane by facilitated diffusion?
a sodium ion
