Cellular Respiration I
What are the three steps of cellular respiration?
What are Glycolysis, Krebs cycle, and Oxidative phosphorylation?
What are the two reactants of cellular respiration?
What is glucose and oxygen?
What are the three products of cellular respiration?
What is water, ATP, and carbon dioxide?
About how many ATP molecules are produced if cellular respiration is successfully carried out?
What is 32-38?
Enzymes _________ reactions in the cells.
What is speed up?
Which step produces the MOST amount of ATP?
What is oxidative phosphorylation or chemiosmosis?
What is the molecule called that glucose splits into after harvesting the energy from it?
What is pyruvate?
Which process of cellular respiration is anaerobic?
What is glycolysis?
The “new” substance created during the reaction.
What is a product?
Enzymes are this type of macromolecule.
What are proteins?
In what part of the cell does glycolysis occur?
What is the cytosol?
ATP has to go through this process to form ADP and Pi.
What is hydrolysis?
What is the main product of alcoholic fermentation?
What are ethanol (alcohol)?
The energy needed to start a reaction is called this.
What is activation energy?
This is what the Enzyme acts upon.
What is a substrate?
What type of fermentation does the human body go through?
What is lactic acid fermentation?
These are used throughout cellular respiration to speed up reactions by lowering activation energy.
What are enzymes?
What are the names of the two electron carriers in cellular respiration?
What is NADH and FADH2?
Explain what is meant by "Enzymes are substrate specific"
What is they only react with certain substrates that fit into the active site. Think Lock and Key!
Where the specific substrate fits in the enzyme.
What is an active site?
The total amount of ATP produced in glycolysis.
What is 4?
This is where H+ are pumped into to form a gradient.
What is the intermembrane space?
What is oxygen considered in the electron transport chain?
What is the final electron acceptor because it is the most electronegative?
This is the main enzyme in the ETC.
What is ATP synthase?
Describe the differences between a synthesis reaction and a hydrolysis reaction.
What is: synthesis is a building up reaction (2 substrates join into one) hydrolysis is a breaking down reaction involving water (1 substrate breaks into two)
