Why does hydrophobic molecules cross the plasma membrane while hydropilic cannot?
Hydrophobic molecules can easily cross the plasma membrane because they are nonpolar and can dissolve in the lipid bilayer, allowing them to pass through without assistance. In contrast, hydrophilic molecules are polar and cannot easily penetrate the hydrophobic core of the membrane, which acts as a barrier to their passage. As a result, hydrophilic substances often require specific transport proteins or channels to help them cross the membrane.
Is there a Krebs cycle in bacteria?
indeed they do..however they do not have a mitochondria which can be the source of the confusion....they do it in a similar space and since they dont have to cross the double membrane of mitochondira they make a net of 38 ATP versus the 36 of eukaryotic cells! indeed they do..however they do not have a mitochondria which can be the source of the confusion....they do it in a similar space and since they dont have to cross the double membrane of mitochondira they make a net of 38 ATP versus the 36 of eukaryotic cells!
The organelle site where most energy is obtained by carbohydrates?
Mitochondria Mitochondria provides the energy a cell needs to move, divide, produce secretory products, contract - in short, they are the power centers of the cell. They are about the size of bacteria but may have different shapes depending on the cell type. Mitochondria are membrane-bound organelles, and like the nucleus have a double membrane. The outer membrane is fairly smooth. But the inner membrane is highly convoluted, forming folds (cristae) as seen in the cross-section, above. The cristae greatly increase the inner membrane's surface area. It is on these cristae that food (sugar) is combined with oxygen to produce ATP - the primary energy source for the cell.
How is the membrane permeability?
means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell
Does egg albumin moves across a plasma membrane?
No, egg albumin is a large protein molecule that cannot pass through the plasma membrane on its own. It would require specific transport mechanisms, such as endocytosis or facilitated diffusion, to cross the membrane.

Why can oxygen easily cross the plasma membrane but sodium ions are unable to cross the plasma membrane?
Oxygen is a small, nonpolar molecule that can cross the plasma membrane via simple diffusion. Sodium ions, on the other hand, are charged and larger molecules that cannot easily pass through the hydrophobic interior of the plasma membrane. Sodium must rely on specific transport proteins like ion channels or pumps to cross the membrane.
Ions cannot cross back and forth across the neuron cell membrane?
Ions can cross the neuron cell membrane through ion channels that open and close in response to various stimuli, allowing for the movement of ions in and out of the cell. This movement is essential for action potentials and communication between neurons.

Find the compound word to cross?
the compound word is cross somebody like if somebodies cross
What ion is found on the inside of a neuron?
The main ions found inside a neuron are potassium and organic anions. The organic anions cannot cross the cell membrane but potassium ions can. It is the diffusion of potassium ions out of the cell which is the main cause of the resting membrane potential.

Which substances are able to cross the membrane, and what determines their ability to do so?
Certain substances, such as small molecules and ions, are able to cross the cell membrane. The ability of a substance to cross the membrane is determined by its size, charge, and solubility in the lipid bilayer of the membrane.
What is the definition of impermeable?
A membrane that lets all materials cross is permeable. A membrane that lets nothing cross is impermeable.
Can pyruvate cross the mitochondrial membrane?
Yes, pyruvate can cross the mitochondrial membrane through specific transport proteins.
