Quick Answer: Where Is The Mitochondria In A Cell?

What is mitochondria in simple words?

Mitochondria (sing.

mitochondrion) are organelles, or parts of a eukaryote cell.

They are in the cytoplasm, not the nucleus.

They make most of the cell’s supply of adenosine triphosphate (ATP), a molecule that cells use as a source of energy.

They oxidise glucose to provide energy for the cell..

What vitamins help mitochondria?

Vitamins B1, B2, B6, niacin, biotin, folic acid and pantothenic acid are important for metabolic pathways in mitochondrial respiration and energy production. Vitamins C, E, niacin and folic acid belong to effective scavengers of free radicals, prevent mitochondrial oxidants formation and mitochondrial aging.

What happens if your mitochondria stops working?

For our bodies the conversion from food energy to ATP happens in mitochondria. If your mitochondria are not working properly then you are less able to convert food into ATP. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.

What happens if the mitochondria is missing?

Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration.

How many mitochondria are in a cell?

The population of all the mitochondria of a given cell constitutes the chondriome. Mitochondria vary in number and location according to cell type. A single mitochondrion is often found in unicellular organisms, while human liver cells have about 1000–2000 mitochondria per cell, making up 1/5 of the cell volume.

How do mitochondria work?

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. NADH is used by enzymes embedded in the cristae to produce ATP.

Which organ has most mitochondria?

heart muscle cellsYour 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!

What color is a mitochondria?

Mitochondria, from liver, concentrated in a pellet are opaque and distinctly yellow in color but when dehydrated and cleared become a transparent red.

Does the mitochondria have a cell membrane?

As previously mentioned, mitochondria contain two major membranes. The outer mitochondrial membrane fully surrounds the inner membrane, with a small intermembrane space in between. The outer membrane has many protein-based pores that are big enough to allow the passage of ions and molecules as large as a small protein.

What do mitochondria look like?

Mitochondria have two membranes (protective coverings) one surrounding the other, called the inner and outer mitochondrial membranes. The inner membrane is highly folded and forms structures called cristae, the machinery for energy generation can be found on these cristae.

Which cells have a lot of mitochondria?

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 helps the mitochondria do its job?

The mitochondria, termed the “powerhouse” of the cell, works with other cellular organelles by providing them with the major form of energy know as adenosine triphosphate (ATP). ATP allows other cellular organelles to function properly maintaing the integrity of the cell.

What are examples of mitochondria?

“What do you mean, example? Mitochondria are the cell organelles where respiration takes place.” “Your junk food unit is usually an demonstration of mitochondria since it gives you power and fire, just as the mtochondria reduces foodstuff substances to discharge electricity.

What is the mitochondria of a cell?

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 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.
