Chapter 7 Flashcards
What is the complete balanced equation for respiration
C6H12O6->6CO2+6H2O+energy(ATP)
What is cellular respiration
The process of breaking down glucose to release energy and form molecules of ATP
What is the C6 molecule initially broken down into?
Pyruvate
Does this breakdown require oxygen
No
What does anaerobic mean?
Without presence of O2 (oxygen)
What is glycolysis? Where does it occur
“Glucose breaking” , cytoplasm
Besides pyruvic acid, what does glycolysis produce
2 ATP and 2 NADH
How many ATPs are formed in glycolysis
2
After glycolysis, how many steps are involved in aerobic respiration?
2
Where does the aerobic stage of respiration take place
Mitochondria
What are the steps in aerobic respiration
Krebs cycle
Electron transport chain
What is another name for the Krebs cycle
Citric acid cycle
Who was it named for
Hans Krebs
What is released as a waste product in the Krebs cycle
CO2
What is the electron transport chain
NADH and FADH formed in the Krebs cycle move from the matrix of mitochondria to the inner membrane called cristae, also called oxidative phosphorylation
Where are the molecules of the electron transport chain located
Cristae
What is the final electron acceptor in the chain
Oxygen
When oxygen accepts the electrons, what is formed?
Water
What 2 compounds so you exhale ? In what processes(be specific) are these products produced?
CO2 (Krebs Cycle), water (ETC)
What is the total number of ATPs that can be formed from the breakdown of one glucose molecule
38 ATP
What are 3 end products of cellular respiration in what processes are each product produced
NADH (Krebs Cycle), FADH2 (Krebs cycle) ATP (Krebs cycle and ETC)
At the end of glycolysis, if no oxygen is present to break down pyruvic acid, what can happen
Fermentation (alcoholic or lactic acid)
Name the two major types of fermentation, how many ATPs are formed in fermentation
Alcoholic and lactic acid, 2ATP
Where does lactic acid fermentation take place ( what type of cells)
Animal cells
What organisms carry out alcoholic fermentation
Bacteria, fungi, and yeast
What are the end products of alcoholic fermentation
Alcohol, CO2, and NAD+
We use fermentation to make what food/drink items?
Alcohol and yeast (bread)
What % of energy is lost if a cell goes through fermentation
98%
Whig is the source of bubbles in an alcoholic beverage?
CO2, it means fermentation is taking place
What are NADH and FADH2
Organic carrier molecules
What is the major function of fermentation
Converting the NADH back to NAD+
List the formula for lactic acid and alcoholic fermentation
Lactic acid : pyruvic acid + NADH -> lactic acid + NAD+
Alcoholic fermentation: pyruvic acid + NADH -> alcohol + CO2+NAD+
