How does a cell transport materials across the cell membrane?

Biology
1 answer:
zavuch27 [327]3 years ago
4 0
Depednign on what the cell is trying to transport there could be a variety of ways for the cell to transfer materials.
If the item is small and np then it can go through the lipid bilayer.



Simple diffusion and facilitated diffusion are passive transport meaning the cell does not need energy to transfer the membrane

and active diffision means they need to spend energy.

you need transmembrane protiens to move things inside the cell

Do all human cells obtain glucose in the same way 
kipiarov [429]

Answer:

Animal cells (including humans ofcourse), heterotrophs, derive their energy from coupled oxidation-reduction reactions. Glucose is a primary fuel for heterotrophs. Energy derived from glucose is stored in the form of high-energy phosphate bonds in ATP, or other nucleotide triphosphates, and as energy-rich hydrogen atoms associated with the co-enzymes NADP and NAD .

Glucose is unable to diffuse across the cell membrane without the assistance of transporter proteins. At least 13 hexose transporter proteins with different functions have been identified. Some hexose transporters allow glucose to flow passively from high to low concentration without requiring the expenditure of cell energy. Those that move glucose against its concentration gradient consume energy, generally in the form of ATP.

D-Glucose is the natural form used by animal cells.

So yes it is present inside human cells .

How many times larger is the number of hydrogen atoms than oxygen atoms in a molecule of water, H2O? ______ b. Is this number th
garik1379 [7]

Answer:

The correct answer is- A) two, B) yes, the number is the same as monosaccharides.

Explanation:

There are three atoms are present in a molecule of water which includes two atoms of the hydrogen and one atom of the oxygen. The hydrogen atom is two times larger in the number of the oxygen atom in a single molecule of the water.

In monosaccharides, the ratio of the atoms of carbon, hydrogen, and oxygen is 1:2:1 which means one hydrogen atom would be twice in the number of the carbon and oxygen atoms in a single molecule of monosaccharide molecule.

Thus, the correct answer is - A) two, B) yes, the number is the same as monosaccharides.
