Please help me with this question. More than one answer may be correct.
The rough endoplasmic reticulum ______.
Options:
A)
is the only site of protein synthesis in the cell.
B)
is a site where glycosylation of proteins takes place.
C)
is a site where cisternal maturation takes place.
D)
is a location where glutamate carboxylation of proteins take place.
E)
has a channel through its membrane called Sec61.
The K+ channel is an example of a transmembrane protein (a protein that spans the phospholipid bilayer of the plasma membrane). What types of amino acids are likely to be found (a) lining the channel through which K+ passes, (b) in contact with the hydrophobic core of the phospholipid bilayer con- taining fatty acyl groups, (c) in the cytosolic domain of the protein, and (d) in the extracellular domain of the protein?
Consider ten glucose molecules that enter a cell. How many ATP can be generated by the complete catabolism of these into CO2 and H2O? If all ten are first incorporated into glycogen, liberated from glycogen, and then fully catabolized into CO2 and H2O, does the ATP tally increase, decrease or stay the same? Consider that 1 UTP = 1 ATP. Explain. Describe the processes which produce ATP and provide a balanced equation of glucose, CO2, H2O and O2

- Glucose is phosphorylated to glucose-6-phosphate by hexokinase in the first step of the glycolytic pathway to trap it in the cell, as G6P cannot diffuse across the lipid bilayer. This reaction also decreases the concentration of free glucose, favoring additional import of the molecule. However, this has a postive standard free energy of 3 kcal per mole. To favor this reaction, hydrolysis of ATP is coupled, which has a standard free energy of -7 kcal per mole. Determine the actual free energy change in kcal/mole for the following conditions: Glucose concentration: 4.5 mM ATP conc: 3.79 mM G6P conc. 0.052 mM ADP conc: 0.12 mM inorganic phosphate conc: 1.3 mM temperature: 313 K Ans. in 3 SFs.arrow_forwardPlease help me with this question.
