Answer the following question given this paragraph: Glycogen Glycogen is the energy reserve carbohydrate of animals. Practically all mammalian cells contain some stored carbohydrates in the form of glycogen, but it is especially abundant in the liver (4%8% by weight of tissue) and in skeletal muscle cells (0.5%1.0%). Like starch in plants, glycogen is found as granules in liver and muscle cells. When fasting, Saylor URL: http://www. saylor. org/books. Q: What term is used to describe the energy reserve carbohydrate of animals? Choices: - lactose - fructose - sucrose - glycogen A:
glycogen

Answer the following question given this paragraph: The fruiting bodies are usually produced at the surface of the food source, rather than hidden within it. This allows the reproductive spores to be easily shed and carried away by the wind, water, or animals. The fruiting bodies are usually the only indication that a fungus is present. Like icebergs, the fruiting bodies represent only a tiny fraction of the whole fungus, with most of the fungus hidden from view. Q: Where is the fruiting body normally produced in relation to the food source? Choices: - at the root - in the soil - underneath the surface - at the surface A:
(Answer)
at the surface
Ques: Answer the following question given this paragraph: When lactose is available, a lactose metabolite called allolactose binds to the allosteric site on the repressor. This interaction causes a conformational change in the repressor shape and the repressor falls off the operator, allowing RNA polymerase to bind to the promoter and initiate transcription. Allolactose is called an inducer because it turns on, or induces the expression of the lac genes. Q: Which inducer turns on the expression of the lac genes? Choices: - xerophyte - glucose - galactose - allolactose A:
Ans: allolactose

Answer the following question given this paragraph: Q: What is a molecule made up of two subunits? Choices: - chloride - enzyme - acid - dimer A:
(A).
dimer
Ques:Answer the following question given this paragraph: conditions. Esters are neutral compounds that undergo hydrolysis, a reaction with water. Under acidic conditions, hydrolysis is essentially the reverse of esterification. When carried out under basic conditions, the process is called saponification. Inorganic acids also react with alcohols to form esters. Some of the most important esters in biochemistry are those formed from phosphoric acid. Amines are nitrogen-containing organic molecules derived from ammonia (NH3). A primary (1) amine (RNH2) has one organic group bonded to the nitrogen atom, a secondary (2) amine (R2NH) has two organic groups bonded to the nitrogen atom, and a tertiary (3) amine (R3N) has three organic groups bonded to the nitrogen atom. Amines are basic compounds that react with strong acids to produce ammonium (NH4+) salts. A cyclic compound in which the ring contains one or more noncarbon atoms is called a heterocyclic compound. There are many heterocyclic amines, including many physiologically important ones. Alkaloids are heterocyclic amines found in many plants. Caffeine, nicotine, and cocaine are familiar alkaloids. Organic compounds containing a carbonyl group bonded to a nitrogen atom are amides, and the carbon-to-nitrogen bond is an amide linkage (or a peptide linkage). Most amides are colorless and odorless, and the lighter ones are soluble in water. Because they are polar molecules, amides have comparatively high boiling points and melting points. Amides are synthesized from carboxylic acids and NH3 or amines. Amides are neutral compounds. They resist hydrolysis in water, but acids, bases, and enzymes catalyze the reaction. Q: Esters are neutral compounds that undergo what process, which is a reaction with water? Choices: - osmosis - cellular respiration - replication - hydrolysis A:

Ans:hydrolysis
Ques:Answer the following question given this paragraph: Remember that a phase change depends on the direction of the heat transfer. If heat transfers in, solids become liquids, and liquids become solids at the melting and boiling points, respectively. If heat transfers out, liquids solidify, and gases condense into liquids. Q: What type of direction does a phase change depend on? Choices: - weight transfer - power transfer - humidity transfer - heat transfer A:

Ans:
heat transfer
