- for every molecule of glucose, ___ molecules of pyruvic acid are formed
- 2 molecules
- Where is energy captured during electron transport
- as electrons move between redox molecules
- Why do leaves appear green
- because chlorophyll reflects away green light
- What does C4 photosynthesis accomplish
- it transports pure CO2 to the Calvin Cycle in plants that grow in warm climates
- Whats the difference between a somatic cell and gamete
- somatic cells undergo mitosis; gametes are reproductive cells
- Where in the cell does glycolysis occur
- cytosol
- What is a possible fate of pyruvic acid
- direct entry into the Krebs cycle
- In photosynthesis, what occurs during electron transport
- energy is harvested as ATP and NADPH
- Glucose molecules are constructed of high-energy carbon-carbon bonds. where does this energy originally come from
- the sun
- Which of the following processes is anaerobic (krebs cycle, electron transport, respiration, or glyoclysis)
- glycolysis
- which of the following helps explain why endurance athletes perform better than sedentary people
- they have more and bigger mitochondria than sedentary people
- How many pairs of homologous chromosomes do males have
- 22
- What are the daughter cells of mitosis
- genetically identical
- oxygen is a byproduct of photosynthesis. what molecule is destroyed to produce it
- water
- What sort of muscle to do you use to train and compete in a marathon
- slow twitch muscle
- what occurs in the Calvin Cycle
- glucose is assembled
- What does Crossing Over Result in
- genetic recombination
- what is the order of the phases of mitosis
- 1) Prophase 2) Metaphase 3) Anaphase 4) Telophase (cytokinesis)
- Where does the light-dependent reaction occur
- in the thylakoid membrane
- What 3 things pass through the stomata
- carbon dioxide, water, and oxygen
- Plants remove CO2 from the atmosphere. What process returns that CO2 to the atmosphere
- Krebs cycle
- when was global warming, as a consequence of human activity, first predicted?
- 1896, by Svante Arrhenius
- How many pairs of homologous chromosomes do females have
- 23
- The United states has 4% of the world's population and produces what percentage of the world's CO2 emissions
- 25 %
- After glyoclysis and the Krebs cycle, most of the energy orginally in glucose is now where
- in NADH
- How does energy first enter into the photosynthetic process
- the energy from a photon is transferred to an electron in chlorophyll
- if yellow peas (Y) are dominant to green peas (y), peas with YY and Yy will have the same
- phenotypes
- What did Mendel's experiments prove
- physical traits are passed from generation to generation in discrete units
- What are the products of Meiosis
- 4 genetically different haploid cells
- why do x-linked conditions appear more frequently in males than in females
- a male with a non-functioning allele on X does not have another allele of that gene
- At what stage in the life of a cell is DNA replicated
- S phase
- What 4 things are effects of global warming today
- 1)record low extent of north polar ice cap 2)acidification of the oceans 3)rising sea levels 4)loss of precise timing of coupled events in ecosystems)
- What role does oxygen have in respiration
- it is the final step; it accepts the electron after electron transport

- NONE (no chance of offspring0
- Why is the Earth suddenly experiencing such a dramatic rise in the average temperature of the Earth
- because burning of fossil fuels releases ten of million of years of CO2, which then strenghtens the greenhouse effect
- The concentration of atmospheric CO2 today is ___ parts per million, which is higher than it has been in at least ___ years.
- 385; 650,000
- When is most of the ATP produced in the break down of glucose for energy

- the plant converts atmospheric CO2 into glucose and, later cellulose
