Cellular Respiration Flashcards
What does aerobic mean?
needs oxygen to release energy into food
What does anaerobic mean?
can release the energy of food without oxygen
What is anaerobic respiration aka?
fermentation
Where does alcoholic fermentation occur?
In yeast
What is first step in cellular respiration?
Glycolysis
What happens during glycolysis?
Glucose (6c) broken into pyruvic acid
How much ATP does it take to split Glucose?
2 ATP
How much ATP does glycolysis produce?
4 ATP
What else does glycolysis produce besides ATP?
NAD+ to NADH
Formula for alcoholic fermentation?
Alchol + CO2 + NAD + (yeast) = alcholic fermenartion
Formula for lactic acid fermentation?
Lactic acid + NAD + (many bacteria) + animals like us = lactic acid fermentation
T or F, fermenation regenerates NAD+
TRUE
What is Krebs Cycle aka?
The Citric Acid Cycle
Where does fermenation occur?
v
WHat happens in the Krebs Cycle?
the 2 pyruvic acids are broken, releasing CO2 and 2 ATP’s, (one from each pyruv)
How many calories make up one Calorie?
1000
Where does glycolysis take place?
In the cell membrane
What is NAD+
an electron carrier
How does NAD+ turn into NADH?
accepts pair of electrons and a hydrogen ion
What is fermentation?
process that releases energy from food molecules by producing ATP in absence of oxygen
Why is Krebs cycle aka the citric cycle?
citrtixc acid is the first molecule produced
What does 1 pyruvic acid produce in kreb cycle?
4 NADH, 1 FADH2, 1 ATP
What happens when carbon dioxide is produced in breaking down of pyruvs?
it is released into the umgebung
What is the electron transport chain?
set of proteins in the mitochondria
What does electron transport chain use the high energy electron for?
converts ADP to ATP
How many ATP molecules are formed during cellular respiration?
36
What are the final waste products of cellular respiration?
CO2 and H2O
