Question

select all statements that accurately describe the structures or functions of mitochondria. mitochondria regulate apoptosis. mitochondria have a permeable inner membrane and an impermeable outer membrane. the configuration of mitochondria does not change. mitochondrial dna is packaged with histones. the synthesis of adenosine triphosphate, atp, occurs inside the mitochondria. mitochondria are included in the endomembrane system.

Explanation:

1. Mitochondria release factors that trigger programmed cell death (apoptosis), so this statement is accurate.
2. Mitochondria have an impermeable inner membrane (for proton gradient) and a permeable outer membrane, so this statement is incorrect.
3. Mitochondria change shape/fission/fusion dynamically, so this statement is incorrect.
4. Mitochondrial DNA is not packaged with histones (unlike nuclear DNA), so this statement is incorrect.
5. Most ATP synthesis occurs via oxidative phosphorylation in the mitochondrial matrix and inner membrane, so this statement is accurate.
6. Mitochondria are not part of the endomembrane system (which includes ER, Golgi, etc.), so this statement is incorrect.

Answer:

• Mitochondria regulate apoptosis.
• The synthesis of adenosine triphosphate, ATP, occurs inside the mitochondria.
