Why Are Mitochondria Called The Powerhouse Of The Cell Quizlet?

What type of cells would have more mitochondria than others?

Some cells have more mitochondria than others.

Your fat cells have many mitochondria because they store a lot of energy.

Muscle cells have many mitochondria, which allows them to respond quickly to the need for doing work.

Mitochondria occupy 15 to 20 percent of mammalian liver cells according to Karp..

What process in the mitochondria breaks down glucose?

In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis. … The mitochondria are the organelles known as the energy “powerhouses” of the cells (Figure below). In the mitochondria, the pyruvate, which have been converted into a 2-carbon molecule, enter the Krebs cycle.

Why do liver cells have lots of mitochondria?

For example, liver cells and muscle cells contain a lot of mitochondria. Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells. They need this because of their frequent contraction and relaxation, which requires more ATP than average cells.

What cells in the human body have the least mitochondria?

The number of mitochondria per cell varies widely; for example, in humans, erythrocytes (red blood cells) do not contain any mitochondria, whereas liver cells and muscle cells may contain hundreds or even thousands. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.

Which process takes place in the mitochondria quizlet?

Mitochondria in cells take up the pyruvate which is formed from glycolysis in the cytoplasm. Once the pyruvate is in the mitochondrion, enzymes within the matrix of the mitochondrion remove hydrogen and carbon dioxide from the pyruvate. This process is called oxidative decarboxylation.

What are the inner folds of the mitochondria called?

Each mitochondrion has two membranes: an inner membrane which is highly convoluted and folded into finger-like projections called cristae, and a smooth outer membrane that is a selective barrier to molecules from the cytoplasm.

Why are mitochondria called the powerhouse of the cell?

Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.

What types of cells would have more mitochondria than others quizlet?

What types of cells would have more mitochondria than others? Animal cells.

What is mitochondria and its functions?

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

What is the cell process that occurs in mitochondria?

Mitochondria: the energy converters Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.

What are the three functions of the mitochondria?

Function. The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration, and to regulate cellular metabolism.

How does the mitochondria produce energy for the cell answers?

The folds inside the mitochondria greatly increases the surface area of the membrane so that glucose can combine with oxygen to produce ATP, (the energy molecule of the cell). molecule together are broken, energy is released for cells to use. Enzymes help to break and reform these high-energy bonds.

How would the number of mitochondria in an insect’s wing?

How would the number of mitochondria in an insect’s wing compare to the amount found in other cells in an insect’s body? Explain your answer. The wings are more active than the rest of the body so the more active it is, the more mitochondria it will have.

Why do heart muscle cells have more mitochondria than other cells in the body?

Our heart muscles contain so much mitochondria because those muscles are very active in our body and require lots of energy to constantly pump blood through our circulatory system. … ATP provides energy for the cell to contract. The more energy any cell needs to generate the more mitochondria it has.

Why do you think some cells have more mitochondria than others?

Some cells have more mitochondria than others because they need to process more glucose and produce more ATP.

What simple sugar is broken down in the mitochondria?

GlucoseGlucose and other carbohydrates made by plants during photosynthesis are broken down by the process of aerobic cellular respiration (requires oxygen) in the mitochondria of the cell. This releases energy (ATP) for the cell.

What can damage mitochondria?

Mitochondrial dysfunction occurs when the mitochondria don’t work as well as they should due to another disease or condition. Many conditions can lead to secondary mitochondrial dysfunction and affect other diseases, including Alzheimer’s disease, muscular dystrophy, Lou Gehrig’s disease, diabetes and cancer.

What is mitochondria in simple words?

Mitochondria (sing. mitochondrion) are organelles, or parts of a eukaryote cell. … They make most of the cell’s supply of adenosine triphosphate (ATP), a molecule that cells use as a source of energy. Their main job is to convert energy. They oxidise glucose to provide energy for the cell.
