Cellular Resp 2. includes idea of NADH and anerobic respiration

Question 1

NADH
-formed by what process
- can be used to make what later
-if oyxgen is present…
-if no oxygen is present
-when complete what has the cell consumed
-what has it produced

Answer 1

-oxidation
-2 ATP later
-pyruvate is transported by carrier protein into the matrix for the link rxn and Krebs cycle
-pyruvate is fremented to make lactose (for ethanol and Co2 in yeast)
-one glucose
-2 NADH molecules, 2 ATP, and 2 pyruvate

Question 1

Glycolysis
-what is it
-occurs in _______
-does or dosen’t required O2
-how many ATP to kick start
-net production of:
-glucose converted to ______ _______ by ____
-unstable molecules all apart into _________
-energy/hydrogen released forms NADH + H+ (________)
-Gp3 converted to_______. Energy released for_____

Answer 1

first step in aerobic and anerobic respiration
-cytoplasm
-dosent require
-2 ATP
-2 puruvic acid (pyruvate), 2 ATP (4 made but 2 required) and 2 NADH (+h+)
-glucose ( 6 carbon) converted to fructose diphosphate by ATP (Phosphorylation)
-2x3 carbon triose phosphate- molecules lysis
-oxidzation
-pyruvate. ATP formation

Question 2

Anerobic Cellular Resp
-glycolysis changes nah+ into
-without a source of ___, glycolysis cant happen because cells have _____
-glycolysis will _____
-evolved in organisms as a ______ so that glycolysis can continue
-one method/process
-anerobic resp=

Answer 2

-NAD+ to NADH
-without a source of NAD+
-limited supply of NAD+
-stop
-recycling way of NAD+
-transferring H’s of NADH+h+ to specific organic molecules called fermentation
-glycolysis+fermentation

Question 3

Lactase Fermentation
-NADH+ anf H+ transfers what
-this regenerates what
-pyruvate changes into what
-this helps maximize what

Answer 3

-2H to pyruvate in the cytoplasm
-NAD+
-into lactic acid/lactase
-helps maximize the power of muscle contractions because they require more ATP than can be produced by aerobic respiration

Question 4

Alcohol (yeast) formation
-pyruvate makes what
-ethanol+NADH +h+ makes what
-recycles what and allows what to continue
-are the 2 atp enough
-will yeast do fermentation when oxygen is available
-carried out by what single celled organisms

Answer 4

-acetaldehyde (ethanol) and CO2
-ethanol and NAD+
-allows glycolysis to continue
-yes
-yes it will do some, which is why bread rises
-fungi like yeast
