Molasses itself is not a permeable membrane; rather, it is a thick, viscous syrup made from sugarcane or sugar beet. Permeable membranes allow certain substances to pass through while blocking others, typically seen in biological contexts, such as cell membranes. Molasses can be used in experiments involving osmosis or diffusion, but it does not function as a membrane in itself. Hence, it does not exhibit the selective permeability characteristic of biological membranes.
What else can I help you with?
Is the membrane permeable to protons?
Yes, the membrane is permeable to protons.
When the bulb of a thistle tube filled with water is sealed by a selectively permeable membrane and submerged in a beaker of molasses the water level in the tube falls.?
When the thistle tube is submerged in molasses, water moves from the tube into the surrounding molasses through the selectively permeable membrane. This occurs because molasses has a higher solute concentration than the water inside the bulb, creating a hypertonic environment. As water leaves the tube to balance the solute concentrations, the water level in the tube falls. This process is an example of osmosis, where water moves toward the area of higher solute concentration.
Is the mitochondrial membrane permeable to protons?
Yes, the mitochondrial membrane is permeable to protons.
What is the basic strcture of a cell membrane?
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
Examples of permeable membrane?
sperm membrane
How is dialysis membrane selectively permeable?
a dialysis membrane is selectively permeable, it is used in experiments to simulate cellular membranes, and it is permeable to water but not to sucrose.
What membrane that allows only some materials to move in and out of the cell is?
Such a membrane is said to be selectively permeable or semi-permeable.
What is a selectlively permeable membrane?
The cell membrane is selectively permeable, allowing some molecules to pass through by osmosis
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.
Which part in the cell is fully permeable and selectively permeable?
The cell membrane is selectively permeable, allowing only certain molecules to pass through based on size, charge, and other factors. Conversely, the nuclear envelope is fully permeable to molecules of certain sizes.
Is cell wall is a permeable membrane?
No, the cell wall is not a permeable membrane. It acts as a rigid structure that provides support and protection to the cell, allowing certain substances to pass through pores, but it is not freely permeable like a membrane.
Is a cell membrane permeable impermeable or partially permeable?
Plasma membranes are selectively permeable.
