Answer the following question given this paragraph: Steps in Glycolysis The 10 reactions of glycolysis, summarized in Figure 20.16 "Glycolysis", can be divided into two phases. In the first 5 reactionsphase Iglucose is broken down into two molecules of glyceraldehyde 3-phosphate. In the last five reactionsphase IIeach glyceraldehyde 3-phosphate is converted into pyruvate, and ATP is generated. Notice that all the intermediates in glycolysis are phosphorylated and contain either six or three carbon atoms. Figure 20.16 Glycolysis. Q: What does glycolysis generate in phase ii? Choices: - amino acids - dna - adp - atp A:
atp
Answer the following question given this paragraph: Q: What is necessary for growth and energy? Choices: - breeding - warmth - determination - nutrients A:
nutrients
Q: Answer the following question given this paragraph: Because alkanes contain only CC and CH bonds, which are strong and not very polar (the electronegativities of C and H are similar; Figure 7.15 "Pauling Electronegativity Values of the "), they are not easily attacked by nucleophiles or electrophiles. Consequently, their reactivity is limited, and often their reactions occur only under extreme conditions. For example, catalytic cracking can be used to convert straight-chain alkanes to highly branched alkanes, which are better fuels for internal combustion engines. Catalytic cracking is one example of a pyrolysis reaction (from the Greek pyros, meaning "fire," and lysis, meaning "loosening"), in which alkanes are heated to a sufficiently high temperature to induce cleavage of the weakest bonds: the CC single bonds. The result is a mixture of radicals derived from essentially random cleavage of the various CC bonds in the chain. Pyrolysis of n-pentane, for example, is nonspecific and can produce these four radicals: Equation 24.7. Q: When do alkane reactions usually occur? Choices: - underwater - at high altitudes - in cold climates - under extreme conditions A:
A: under extreme conditions
Question: Answer the following question given this paragraph: Biochemical reactions are optimal at physiological temperatures. For example, most biochemical reactions work best at the normal body temperature of 98.6F (37C). Many enzymes lose function at lower and higher temperatures. At higher temperatures, an enzyme's shape deteriorates, and only when the temperature comes back to normal does the enzyme regain its shape and normal activity. Q: Biochemical reactions are optimal at physiological temperatures because many what lose function at lower and higher temperatures? Choices: - hormones - carbohydrates - neurons - enzymes A:
Answer: enzymes

Answer the following question given this paragraph: Earth's atmosphere is vital to life. The atmosphere provides the oxygen and carbon dioxide living things need for photosynthesis and respiration. Living things also need the ozone layer high in the atmosphere. Upper level ozone protects them from most of the Sun's harmful UV rays. Q: What layer high in the atmosphere protects living things from most of the sun's harmful uv rays? Choices: - Mesosphere - troposphere - stratosphere - ozone layer A:
**Answer**
ozone layer
