What is the term for hormones that are lipid-soluble and can pass through cell membranes?
steroid hormones
How does thyroxine pass through the plasma membranes?
diffusion. it is lipophilic and is able to pass through the PM. thyroxine is not water soluble and is the reason why it requires a carrier protein (albumin) for circulation.
Proteins do not pass through cell membranes because?
g
What kind of things can pass through the phospholipid bilayer?
Lipid-soluble molecules, such as oxygen, carbon dioxide, and steroid hormones, readily diffuse through plasma membranes. Water, however, requires small pores called aquaporins therefore it is aided.
Why is detergent added to the extraction buffer?
The detergent was added because it breaks open the cells by destroying fatty membranes that enclose the cell, thus releasing the DNA into the solution.
What is the term for hormones that are lipid-soluble and can pass through cell membranes?
steroid hormones
Why can molecules that are fat soluble permeate across a cell membrane?
because the external surface of the cell is is hydrophobic (water hating) many fat soluble products such as carbon dioxide are able to pass through.
How does the Oxygen get from the interstitial fluid to the inside of the cell?
Oxygen is lipid soluble therefore it can pass directly through the cell membranes of the capillaries.
Why can molecules that are fat-soluble permeate across a cell membrane?
Cell membranes are composed of a lipid bilayer. Cellular fluid (cytosol) and the cell's organelles are contained by the cell's membrane, which is composed of a lipid bilayer. Lipids are a type of fat. Because a cell's membrane is composed of fat, only fat-soluble molecules are able to dissolve through the membrane into the cytosol.
Why does NaCl not require a transport protein for diffusion?
It does require a transport protein as it disassociates into charged ions and it is not lipid soluble. Only lipid soluble molecules diffuse freely through living membranes.
How does thyroxine pass through the plasma membranes?
diffusion. it is lipophilic and is able to pass through the PM. thyroxine is not water soluble and is the reason why it requires a carrier protein (albumin) for circulation.

Why can carbon dioxide move easily through a membrane?
Carbon dioxide is a relatively small molecule, and can diffuse through semi-permeable membranes easily, providing that it moves down a higher concentration gradient.
Water passes through a cell membrane by?
What_is_the_passage_of_water_through_cell_membranes_calledPassage of water through cell membranes occurs through osmosis.
How does carbon dioxide gets out through the cardiovascular and the respiratory systems?
The blood carries carbon dioxide waste from the tissues where it's generated. When this carbon dioxide reaches the capillaries at the alveoli, it diffuses across the membranes and is released during exhalation.
Why was detergent added to extraction buffer?
because it can break through the membranes to get to the DNA
How does Cortisone easily travel through the epidermis?
Cortisone is lipid solubleLipid-soluble substances can penetrate through the skin through the lipid bilayers of the plasma membranes of the epidermal cells
