Acetyl-CoA is further metabolized in what part of cellular respiration?
Krebs Cycle (citric acid cycle)
Where does the Kreb's Cycle take place?
mitochondrial matrix
When is the most ATP formed during cellular respiration? The net movement of what causes this to happen..
ETC and ATP synthase; H+(protons) move down the concentration gradient
What are some similarities between ATP synthesis in the mitochondria and chloroplast?
electron transport chains create a gradient of protons (H+) so that ATP synthase can generate ATP molecules
What is a dependent variable? Give an example from one of our labs in this unit.
what is measured or observed in an experiment (amount of O2 production, amount of CO2 production)
If your data consists of pH changing over time, what kind of graph would be most appropriate to use?
line graph
How do you know when there is statistical difference in data?
when there is no overlap in the data (+-2SEx) - looking at error bars on a graph
Which two substances produced in the light-dependent reactions provide energy for the light-independent reactions?
ATP and NADPH
What is chemiosmosis? What provides the energy for this to happen in cellular respiration?
the diffusion of ions through a membrane; electrons flowing through the ETC
What are the functions of NAD+ and FAD in cellular respiration?
accepting electrons during the oxidation-reduction reactions
Why can more ATP be produced from an NADH molecule vs a FADH2 molecule?
NADH drops electrons off at protein complex 1 and they travel through four complexes, FADH2 drops electrons off at complex 2 and they only go through 3 complex
Germination in seeds would be increased by the exposure to ____.
light, more water, higher temperatures, more carbon dioxide
What is required during photosynthesis to energize electrons to be transported in the ETC?
light
What is a positive control?
a control group where you expect a certain result to happen
