Respiration Flashcards
What is the main source of energy in cells?
Glucose
What is the type of energy stored in glucose?
Chemical energy
What is the energy released from the breakdown of glucose used to make?
ATP
Where does respiration begin?
In the cytoplasm
Where is aerobic respiration completed?
In the mitochondria
What are 2 cells that require a lot of energy?
Sperm cells and muscle cells
How much ATP is produced in the breakdown of glucose to pyruvate?
2 ATP
Describe the first step of respiration?
Glucose is broken down into 2 molecules of pyruvate
Describe the second stage of respiration if oxygen is present?
Pyruvate travels to the mitochondria and if oxygen is present it is broken down into carbon dioxide and water. A large amount of energy is also released
What is the word summary for aerobic respiration?
Glucose + Oxygen > Carbon dioxide + water + energy
What is the word summary for fermentation in animal cells?
Glucose > Lactate + Energy
What is the word summary equation for fermentation in plant and yeast cells?
Glucose > Carbon dioxide + Ethanol + Energy
What is the name e
given to respiration taking place in the presence of oxygen?
Aerobic respiration
Where is fermentation completed?
In the cytoplasm
What cellular activities can the energy released be used for?
State 2
Muscle contraction, cell division, protein synthesis
