Where are most carbohydrates found on a membrane?
Carbohydrates are not present on the membrane.
the transmembrane region
the outer surface
both the inner and outer surface of the membrane
the inner surface
Which of these is NOT a true statement? All cells contain cytoplasm. All cells contain DNA. All cells have plasma membranes. All cells contain mitochondria. All cells contain ribosomes.
Which of the following is found in eukaryotic cells but not in prokaryotic cells? a nucleus a cell membrane DNA enzymes a cell wallIf you label two different cells with different fluorescent labels and then fuse the two cells, the membrane components become evenly distributed across the membrane of the hybrid cell. What can you conclude? Membrane components are moving within the membrane. Membrane components are fixed within the membrane. Fluorescent labeling is not a useful technique for studying membrane components. The cells should have been labeled with the same fluorescent labels. None of the answers are correct.
if a bottle of nail polish remover contains 172ml of acetone how much heat would be released by its complete
How many atoms of He gas are present in a 450 mL container at 35°C and 740 mmHg
Calculate the final temperature of an aqueous solution if 30g of CaCl2 is added to 100 mL of water at 23 degrees celcius. Assume that the specific heat of the solution is the same as that of water= 4.184 J*g/celcius
Explain which element is the central atom, define how many bonds does the central atom form, is it polar or non-polar, explain what the direction of negativity is
You are to prepare a buffer at a pH of 9.00 using 0.50 mol/liter HCN and 0.36 mol/liter NaCN. If you begin with 250.0mL of 0.36 mol/liter NaCN, how many liters of the HCN solution must be added to the NaCN to prepare the buffer
NO is produced in the atmosphere at moderately low partial pressure by high temperature combustion. What is its fate as cooling occurs? To help address the question, calculate the equilibrium constant at 298 K and 1300 K for each reaction
What volume of a 35.0 mM solution of propionic acid is required to supply
Suppose that a linear Na11 molecule could be formed by combining the 3s orbitals on each atom into delocalized MOs. How many nodal planes are in the highest occupied molecular orbital (HOMO) of this molecule
In aqueous solution, amphipathic molecules form aggregates of micelles or bilayers that maximize hydrophobic interaction. Describe and draw what would happen if instead of an aqueous solution, amphilic molecules were dissolved in an organic solven..
Question- Strong base is dissolved in 525 ml of 0.200 M weak acid (Ka = 3.94*10^-5) to make a buffer with a ph of 4.20. Assume that the volume remains constant when the base is added. How many moles of strong base were initially added
A pentapeptide was found to contain the amino acids Phe, Gly, Met, Ala, and Ser. N-Terminal analysis yielded the PTH derivative of alanine. Partial hydrolysis of the pentapeptide yielded the dipeptides Gly-Ser, Ala-Gly, and Ser-Met.
