High School Biology › Understanding Mitochondria and Chloroplasts
Which of the following organelles is commonly referred to as the powerhouse of the cell?
Which of the following organelles contain their “own” DNA?
How is mitochondrial DNA (mDNA) different from nuclear DNA?
Where does the Krebs cycle take place in the mitochondria?
All of the following are true of chloroplasts except __________.
The mitochondria are commonly considered the powerhouses of the cell. The energy (ATP) necessary for cell function is created within the mitochondria via the process of oxidative phosphorylation (the electron transport chain). In order for oxidative phosphorylation to be effective, certain proteins must maintain a proton gradient between the two membranes that surround the mitochondria.
Studying the structure of the mitochondria, you will notice that the organelle has two membranes. The outer membrane is smooth, while the inner membrane has numerous inversions and folds. These folds are called cristae. What is the purpose of the cristae?
Which of the following cellular organelles is responsible for making a majority of the cell's energy?
Which of the following is not true regarding mitochondria and chloroplasts?
What is the "powerhouse" of the cell?
What organelle is associated with photosynthesis in algae?
