Cellular Respiration

HBIO3 unit 9ish

QuestionAnswer
Cellular Respiration formula 6O2 + C6H12O6 --> 6CO2 + 6H2O
Cellular Respiration is how we convert food to energy - how we make ATP out of glucose
Glycolysis -occurs in the cytoplasm -breaks glucose down -is an anaerobic process (doesn't need o2)
Kreb's cycle - Citric Acid cycle and the ETC -happens in mitochondria -aerobic process (needs o2)
Glycolysis process -2 ATPs are used to break glucose down, becoming 2 ADP -2 NAD+ become 2 NADH and 4 ADP becomes 4 ATP using E from the breaking bonds -2 pyruvic acids/pyruate are made from the broken down glucose Net gain of 2 ATP
Acetyl CO-A rxn 1 carbon in the pyruvate combines with O2 and leaves as CO2, leaving behind the 2 other carbons that are now Acetyl CO-A
Kreb's cycle process -The 2 remaining carbons from the Acetyl CO-A rxn combine with 4 carbons to make a 6 carbon mole. (citric acid) -1 carbon leaves as CO2 making another NADH -1 more carbon leaves as CO2 and a NADH, ATP, FADH2, and 1 more NADH are made
ETC process -NADH + H+ becomes NAD+, leaving behind 2 e- -FADH2 drops off 2 more e-, becoming FAD -2H+ combine with O2 and 2 low E e- to create H2O -H+ are moved by e- to ATP synthase, they spin the ATP synthase to create E and ADP combines with Pi to make ATP
Lactic acid fermentation happens when there is not enough O2 in the ETC, which backs up the e-, which backs up the H+ making the environment too acidic (too much H+) The NADH then gets backed up so no more NAD+ which means no more Glycolysis
Lactic acid fermentation process -Glucose is turned into 2 pyruvate during glycolysis -The NADH made during glycolysis is recycled to make a little more ATP -The pyruvate becomes 2 lactic acids/lactate (Pyruvate + H+ + e-) ?? (i don't understand this)
The electron carriers of cellular respiration are made during glycolysis and the kreb's cycle and carrie high E e- to ETC -NADH (NAD+ + H+ + 2e-) -FADH2 (FAD + 2H+ + 2e-)
one mole. of sugar/glucose produces how many ATP when O2 is present 36 ATP
The products of the Kreb's cycle are NADH and FADH2 - they go to the ETC
For each mole. of glucose used in the Kreb's cycle (Blank) ATP is made 2 ATP
H2O equation in the ETC 2e- + 2H+ + 1/2O2 = H2O
The products of the ETC are H2O and ATP
How many ATPs are made in glycolysis, the Kreb's cycle, and the ETC 2 ATPs are made in glycolysis 1 ATP is made during the Kreb's cycle 32-34 ATP is made in the ETC
Each FADH2 can generate (blank) ATPs 2 ATPs
Cellular respiration can produce up to (blank) ATPS 36 ATPS

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
