What does cellular respiration do to a cell?
Withdrawals energy
100
Is energy required or released in photosynthesis?
It requires energy
100
How is lactic acid produced in your body?
It is produced during rapid exercise when the body can not supply enough oxygen
100
Glycolysis is a _______ process.
Energy releasing
100
When does the Krebs Cycle begin?
When pyruvic acid produced by glycolysis enters the mitochondrion.
200
What is the process of cellular respiration?
Releases energy by breaking down glucose and other food molecules in the presence of oxygen.
200
Which organelle does photosynthesis occur in?
Chloroplast
200
What is produced by lactic acid fermentation?
ATP
200
The process is so fast that cells can produce thousands of_________ molecules in just a few milliseconds.
ATP
200
What can the ATP produced directly in the Krebs Cycle be used for?
Cellular activities
300
Which organelle does it occur in?
Mitochondria Glycolysis
300
What does photosynthesis do to a cell?
It deposits energy
300
What is the result of built up lactic acid in your muscles?
Painful burning sensation
300
What is glycolysis?
The breakdown of glucose by enzymes, releasing energy and pyruvic acid.
300
The Krebs Cycle is also known as the ______ Cycle
The citric acid cycle
400
Which organisms does cellular respiration occur in?
All living organisms
400
Does photosynthesis produce ATP?
Yes
400
What does the process of lactic acid fermentation regenerate?
NAD+
400
If oxygen is not present, glycolysis is followed by a _____ pathway.
Different
400
The Krebs cycle generates high energy electrons that are passed to _______- and ______.
NADH and FADH2
500
What is the main function of cellular respiration?
Breaks down food and energy is released
500
What are the reactants of photosynthesis?
6CO2 and 12H2O and light energy
500
What is the equation for lactic acid fermentation after glycolysis?
pyruvic acid + NADH ->lactic acid + NAD+
500
What is the equation for glycolysis?
C6H12O6 + 2ATP -> 2 pyruvate + 4 ATP + 2 H2O
500
What happens during the Krebs Cycle?
Pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions.
