* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.
* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.
Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.
A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules
The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.
GLUCOSE IS CONVERTED INTO CELLULOSE FOR MAKING CELL WALLS. GLUCOSE IS COMBINED WITH NITRATES (COLLECTED FROM THE SOIL) TO MAKE AMINO ACIDS, WHICH ARE THEN MADE INTO PROTEINS. GLUCOSE IS TURNED INTO LIPIDS FOR STORING IN SEEDS.
Jupiter, because its the biggest.
A is correct. DNA replication is just a different way of saying Meiosis II.
Answer:
Just looking at these answers none of them seem particularly right as sunlight is used as the energy source to make glucose meaning that it is used as energy to bond hydrogen, carbon, and oxygen. The most right answer however i think is that it is converted into chemical energy.
