GENERAL INFORMATION
What is aerobic respiration?
What is anaerobic respiration? How much ATP does it produce?
What is cellular respiration? How much ATP does it produce?
What are redox reactions? What is oxidation (gain or loss of electrons?)? What is reduction (gain or loss of electrons?)?
Explain in term of cellular respiration why we breathe oxygen, and exhale carbon dioxide?
What is the difference between substrate level phosphorylation and chemiosmotic (or oxidative) phosphorylation?
GLYCOLYSIS
Where does glycolysis occur?
What are the net (Total/overall) products of glycolysis?
Why do we invest energy to make glycolysis occur?
How much of the energy available in a glucose molecule is harvested as ATP in glycolysis?
If oxygen is present, where does pyruvic acid go? What happens to it?
If oxygen is not present, where does pyruvic acid go? What happens to it?
Why would yeast choose to perform anaerobic respiration, as in our lab, even though oxygen was available to them?
FERMENTATION
What is the purpose of fermentation? (What does it recycle for glycolysis to continue?)
When does fermentation take place?
What does a build up of lactic acid cause in our bodies?
KREBS CYCLE
Where does the Krebs cycle take place?
What are the net (Total/overall) products of the Krebs cycle? For each acetyl coA molecule? For each glucose molecule?
How is pyruvic acid changed before it will enter the Krebs cycle?
What is the primary energy carrier that is produced in the Krebs cycle?
ELECTRON TRANSPORT CHAIN (SYSTEM)
Where does the electron transport chain take place?
What are the net (Total/overall) products of the ETC?
What molecules enter the electron transport chain?
What specifically happens to the electrons in the ETC? What is the final electron acceptor in this system? What happens to that product after it initially accepts electrons?
How is the transport of H+ ions linked with the ETC? Why is this important?
What does the proton gradient drive the ATP synthase? Why does it only happen at this specific location in the membrane (i.e. why can’t the H+ ions move across the membrane at any point)?
Chapter 7 - Photosynthesis
What is the path an electron takes through photosynthesis?
What is the balanced equation for photosynthesis? What is reduced and what is oxidized?
What is an autotroph? A producer? (What are we?)
Why is chlorophyll green? What wavelength (in nm) does it reflect?
Describe the anatomy of a leaf. What is the stomata and what happens here? The thylakoid – what is present and what occurs? The chloroplasts – what happens here? The grana? The stroma – what happens here?
What are the light reactions? What happens and what is created?
What is the dark reaction? What happens and what is created?
What is a photosystem? What is the difference between Photosystems I and II?
What is the reaction center? What are antenna molecules? Where do the electrons come from that are put into the photosystem and eventually move to the primary electron acceptor?
What are the differences between the electron transport chains in the mitochondria and the ETCs in the thylakoid?
How many times the Calvin cycle have to turn to produce on G3P? one glucose? How much CO2, ATP and NADPH does each of these consume?
How do plants store their excess sugar?
What is carbon fixation?
Chapter 8 - Mitosis and
1. Know the multitudinous definitions that are in the chapter: sexual reproduction, asexual reproduction, life cycle, chromosomes, chromatin, sister chromatids, centromere, cell cyle, mitosis, mitotic spindle, kinetochore, cleavage furrow, cell plate, anchorage dependence, density-dependent inhibition, cell cycle control center, tumor, malignant vs. benign tumors, metastasis, somatic cell, homologous chromosom, autosomes, diploid, haploid, gametes, fertilization, zygote, meiosis, crossing over, chiasma, genetic recombination.
2. karyotype, trisomy 21 (Down’s syndrome), nondisjunction, deletion, duplication, inversion, translocation. You do NEED to know these terms, this is a correction from the first email.
3. What are the four phases of mitosis and meiosis? What similarities exist in these phases between mitosis, meiosis I and meiosis II? What makes them different? Which one process (mitosis, meiosis I and meiosis II) is most different from the others? Explain your answer.
4. How much time of the entire cell cycle is spent in Interphase? M phase?
