Cell resp. pt 1
What does cellular respiration produce?
ATP molecules with high potential energy
*often uses glucose for that
What are the three components of glucose processing?
-the krebs cycle
-electron transport coupled with oxidative phosphorylation
formula of combustion of glucose
When do plants make glucose?
How is glucose often stored as? (3)
starch, glycogen, fats
What is glucose used for?
From what processes can ATP be made from?
fermentation and respiration
What does ATP consist of?
-3 phosphate groups
(atp consist of) How are ribose and adenine linked?
through covalent bond
(ATP made of) what is main source of energy in ATP?
Diagram of ATP
Whats ribose (small description) (2)
-important sugar in RNA and ATP
Diagram of Ribose linear
Diagram of ribose ring structure
What type of sugar is often marketed for bodybuilding purposes?
Brief description of adenine (2)
-one of bases found in DNA
-is used to carry energy from one molecule to another
Diagram of adenine
-this reaction is highly exergonic
*gives off alot of energy
What does phosphorylation lead to?
changes shape of protein and activity
What is phosphorylation?
-phosphate that binds to protein
(slide 15) PArt A= Glycolysis
-glucose will go through series of reactions that will end up becoming pyruvate, a small ATP production, and NADH
(slide 15) Part B= Pyruvate processing and krebs cycle (4)
-pyruvate goes into mitochondria
-enzymes will produce CO2 and NADH
*rest goes into krebs cycle
-After series of reactions in Krebs cycle, CO2 + ATP + NADH FADH is released
(slide 15) Part C= Electron transport and oxidative phosphorylation (3)
-move energetic electrons across proteins
-oxygen will move into the proton gradient
-ATP and H2O will be made
Slide 16= NAD+ and NADH diagram
(slide 16) What does NAD+ contain?
adenine, ribose, 2 phosphates (all three made ADP) , ribose, and a ring molecule
(slide 16)(Ring molecule NAD+) Ring moleucle will..
go through a process called reduction
(slide 16)What happens to NAD+ in reduction process?
-takes on H+ and 2 electrons to become NADH
(slide 16) How does NADH become a NAD+?
NADH gives up its electron and proton
(slide 18) The atom that has been
does it have more or less electrons?
(slide 18) Which has the highest form? Oxi or red?
*oxi loses energy
Oxi or red?
Reduced because carbon gains electrons
NAD+ is the Oxi or red?
(oxi and red pneumonic) When a molecule is reduced...
the postive charge is reduced
(oxi and red pnuemonic) LEO the lion goes GER
lost of electron= oxidation
Gain of electron= Reduced
NAD stands for?
From where does the word nicotine come from?
-plant called nicotiana
*named after french that introducced tobacco
Ultimate source of energy for contructing ATP is
Average dialy intake of 2500 calories translates to..
turnover of 180 kg of ATP
