1. Replace the elements of the mitochondrion:
a. External membrane
b. Internal membrane
c. DNA
d. Ribosomes
e. Mitochondrial comb
e. Matrix
2. What is the function of mitochondrion.
a. They produce energy in the form of high – energy ATP.
b. Catalyze the conversion of pyretic acid.
c. Acetylokoenzym oxidizes the citric acid cycle.
d. They are responsible for carrying out the various stages of protein
synthesis.
3. Mitochondria
• Are surrounded by are single membrane
• Are surrounded by a double membrane
• They are not surrounded by any membrane
• They are autonomous organelles
4. It is not true that mitochondria:
• Are only in eukaryotes
• They contain their own DNA
• They come from single-celled eukaryotes
• Provide biologically useful energy
