What substances are found in mitochondria?
Inner membrane structure of the mitochondria. Mitochondria contain deoxyribonucleic acid (DNA) and ribosomes, protein-producing organelles in the cytoplasm. Within the mitochondria, the DNA directs the ribosomes to produce proteins as enzymes, or biological catalysts, in ATP production.
What are the two substances produced in the mitochondria?
The mitochondria take food molecules in the form of carbohydrates and combine them with oxygen to produce the ATP. They use proteins called enzymes to produce the correct chemical reaction. Mitochondria have a distinct structure that helps them to generate energy.
Where is the mitochondria in a plant cell?
cytoplasm
Mitochondria are located in the cytoplasm of cells along with other organelles of the cell.
What organ has a lot of mitochondria?
A. Your heart muscle cells – with about 5,000 mitochondria per cell. These cells need more energy, so they contain more mitochondria than any other organ in the body!
Where does most of the energy production of mitochondria take place?
Energy production mostly takes place on the folds or cristae of the inner membrane. Mitochondria convert chemical energy from the food we eat into an energy form that the cell can use. This process is called oxidative phosphorylation. The Krebs cycle produces a chemical called NADH.
How are mitochondria involved in the destruction of cells?
Mitochondria help decide which cells are destroyed. Mitochondria release cytochrome C, which activates caspase, one of the chief enzymes involved in destroying cells during apoptosis.
Where do molecules cross the inner membrane in the mitochondria?
Molecules can only cross the inner membrane in special membrane transporters. The inner membrane is where most ATP is created. Cristae: These are the folds of the inner membrane.
Why do different types of cells have different numbers of mitochondria?
Mitochondrial DNA is housed here (see below). Different cell types have different numbers of mitochondria. For instance, mature red blood cells have none at all, whereas liver cells can have more than 2,000. Cells with a high demand for energy tend to have greater numbers of mitochondria.
