What are the differences between the “Cheesy Way to Measure Calories Lab” and cell respiration?
Lab (burning food) does not actually consume and break down food like cell respiration does, but instead burns. It takes place outside of a living organism and causes a chemical reaction to create energy w/o being a biological process in the body.
Where does the matter and energy come from that originally makes the food (peanuts, etc.)?
CarbonDioxide !!!
Why ATP?
ATP (adenosine triphosphate) is a manageable source of energy and powers many of our cellular processes
How is ATP made?
Cellular Respiration & Light Reaction process during photosynthesis
Why is the reaction “ADP + P → ATP” an energy requiring reaction?
The phosphates are negatively charged
Why is the reaction ATP → ADP + P an energy releasing reaction?
The separation of two negatively charged phosphates releases energy
Glycolysis occurs in both aerobic and anaerobic respiration: T or F
TRUE
What is the equation for cellular respiration?
C6 H12 O6 + 6 O2 → 6 CO2 + 6 H2O (+ ATP)
What is the equation for photosynthesis?
6 CO2 + 6 H2O → C6 H12 O6 + 6 O2
Glycolysis splits glucose into ..
PYRUVATE
The 2 Pyruvate from Glycolysis are transferred..
Into the mitochondria using active transport
When Pyruvate is in mitochondria, what happens to it?
It is oxidized and converted to 2 acetyl COA
What leaves as Pyruvate converts to 2acetyl COA?
Carbon Dioxide (CO2), NADH is produced
KREBS CYCLE!!! AHHH what happens?!?
COA is like bye gurl to Ms. Acetyl -> Ms. Acetyl (2c) moves on to Mr. Oxaloacetate (4c) -> leading them to SIT together and become #Citrate. BUT!!! 2 CO2 leave, converting #Citrate into only #Oxaloacetate. In this process of Mr. Oxaloacetate becoming single again, he lets out tears of Hydrogen ions, which 3NAD steal to become 3NADH and FAD to FADH. All his crying builds up to release ATP!! Then Mr. Ox goes back to find Ms. Acetyl (cycle repeats).
Describe the process in the Electron transport chain
Electron carriers are filled with Electrons dropped off by NADH (which leaves as NAD), and FADH, (which leaves as FAD).
Hydrogen ions from NADH and FADH enter the inner mitochondria membrane, where it builds up to a super high concentration.
As the electron nears the end of the chain, oxygen accepts it with a hydrogen ion and becomes water (product).
Hydrogen ions release thru ATP synthase so fast that phosphates bond with ADP to create ATP (product).
