Cellular Respiration Basics
The overall purpose of cellular respiration is to produce this molecule for energy.
What is ATP?
This is the first step of cellular respiration where glucose is broken down.
What is glycolysis?
This is the type of respiration that does not require oxygen.
What is anaerobic respiration?
Oxygen is essential in cellular respiration because it serves as the final acceptor of these particles.
What are electrons?
This is the process by which cells convert glucose into energy in the form of ATP.
What is cellular respiration?
This organelle is the site of cellular respiration.
What is the mitochondrion?
This cycle, also called the citric acid cycle, occurs in the mitochondrial matrix.
(Hint:This cycle produces NADH)
What is the Krebs cycle?
Anaerobic respiration in muscles can lead to the buildup of this compound, causing soreness.
What is lactic acid?
Without oxygen, cells switch to this less efficient process to produce ATP.
What is fermentation?
The Krebs cycle is also known by this name, which refers to its discovery by a British biochemist.
What is the citric acid cycle?
This three-carbon molecule is the product of glycolysis.
(Hint: It's a kind of acid.)
What is pyruvate?
During glycolysis, glucose is broken down into two of these molecules.
(Hint: This three-carbon molecule is created when glucose is split in half during glycolysis.)
What are pyruvate molecules?
Alcoholic fermentation produces ethanol and this gas.
What is carbon dioxide?
This structure in the human body is responsible for oxygen exchange with the blood.
What are the alveoli?
This term describes the oxygen-dependent pathway of energy production that occurs in the mitochondria.
What is aerobic respiration?
Glycolysis occurs in this part of the cell.
What is the cytoplasm?
This molecule is the final electron acceptor in the electron transport chain.
What is oxygen?
Yeast performs this type of respiration when oxygen is unavailable.
What is fermentation?
During intense exercise, muscles may switch from aerobic respiration to this process.
What is anaerobic respiration?
The net gain of ATP molecules from one molecule of glucose during glycolysis is this number.
What is 2 ATP?
The electron transport chain is located on this structure within the mitochondria.
What is the inner mitochondrial membrane?
The Krebs cycle produces this gas as a waste product.
What is Carbon Dioxide/CO2?
This is the total number of ATP molecules produced in aerobic respiration.
What is 36-38 ATP?
In cellular respiration, oxygen combines with these to form water.
What are hydrogen ions (or protons) and electrons?
This gas is produced as a byproduct of aerobic respiration in animals and is released during exhalation.
What is carbon dioxide or CO2?
