Review Questions:
What are 3 things needed for cellular respiration and ATP production?
oxygen, glucose, ___
When oxygen is not present, what is pyruvate converted into?
What are the three processes in cellular respiration?
Glycolosis, citric acid cycle. oxidative phophoralation
What are the starting reactiant and the end products of glycolysis
glucose, NAD+, ATP….4 qatp, 2nadh, 2 pyruvate
Name the reactants and products of oxidative metabolism – overall reaction
NADH FADH2. .product: 32-34 atp
What is the role of NAD+
a H+ shuttle to bring to Electron transport system
How many ATP are produced per glucose molecule?
What makes lactic acid fermentation and alcohol fermentation different?
lactic:converts pyruvate to lactic acid. reversible. Fermentation:
pyruvateethanol. irriversable. releases co2
Where does glycolysis and Kreb’s cycle take place?
glycolysis: happens in cytosol. krebs in mitochondria
What is occurring when a reaction reaches equilibrium?
reactants=to products
