Question
Chapter 23, Problem 41P
Interpretation Introduction
Interpretation:
Degradation signals and protein-protein interactions are generally present in protein regions. The explanation for the coexistence of these two functions in the same domain can be useful.
Concept introduction:
Protein-protein interaction networks or PPIN are the mathematical representations of the physical relations present between the proteins of the cell. These relations are definite and occur between demarcated binding regions in the proteins. They have a specific function.

Sort the descriptions into properties that describe either saturated phospholipids or unsaturated phospholipids.
Saturated phospholipids
Saturated and
unsaturated phospholipids
Unsaturated phospholipids
Answer Bank
have no double bonds in the fatty acid carbon chains
have straight fatty acid tails
have at least one double bond in the fatty acid tails
have bent fatty acid tails
are built upon a glycerol backbone
make the membrane somewhat rigid at low temperatures
allow the membrane to remain fluid and flexible at low temperatures
fatty acid tails pack tightly together
maintain some space between adjacent phospholipids
Place the events of an action potential in order, starting and ending with a cell at its resting membrane potential.
Cell starts at its resting membrane potential.
Cell returns to its resting membrane potential.
Answer Bank
K+ channels fully open, and Na+ channels are inactivated.
K* rushes out of the cell, causing repolarization.
K+ channels close slowly, resulting in hyperpolarization. Na+ channel gates reset.
Fast Na+ and slow K+ channels are activated. Na rushes into the cell, causing membrane depolarization.
Ligand activation of the acetylcholine receptor depolarizes the membrane.
Glucose and fructose are reducing sugars. Sucrose, or table sugar, is a disaccharide consisting of both fructose and glucose.
Is sucrose a reducing sugar? Why or why not?
No, because only one anomeric carbon is involved in the glycosidic linkage.
No, because both anomeric carbons are involved in the glycosidic linkage.
Yes, because the fructose unit can convert to the open-chain form.
Yes, because the glucose unit can convert to the open-chain form.
Which statements about reducing sugars are true?
The oxidation of a reducing sugar forms a carboxylic acid sugar.
D-Arabinose (an aldose) is a reducing sugar.
Reducing sugars contain keto groups instead of aldehyde groups.
A disaccharide with its anomeric carbons joined by the glycosidic linkage cannot be a reducing sugar.
A reducing sugar will not react with the Cu² + in Fehlings's reagent.

What is the biochemical rationale for the use of creatine? It would directly serve as an electron carrier to support the oxidation of fuel molecules and thus energy production. It would serve as an electron donor to support reductive biosyntheses required to sustain cellular function. It would be converted into creatine phosphate and thus serve as a rapid means of replenishing ATP during muscle contraction. It would promote the movement of ions through ion channels and thus power the synthesis of ATP during exercise.
