Q:

What are plant cells mitochondria?

A:

Quick Answer

The mitochondria is the location inside the cell where the energy, called adenosine triphosphate, or ATP, is made. This specific part of the cell is composed of rod-shaped organelles. Mitochondria are the animal-version chloroplast, where the energy cycle in plants takes place.

Full Answer

In a normal animal or human cell, there can be anywhere between a thousand and two thousand mitochondria. The energy created by organelle is done through the process of cellular respiration. Every living cell in an organism contains this structure because every living cell plays a role in respiration. Even though these structures are important in the cells, they only range in size between a half and one micrometer. Along with being the main area of energy production, the mitochondria play a part in a number of other functions including cell signaling, growth and cell cycles. The structure has both an inner and outer membrane, which contain a large number of very important proteins. The outer membrane contains proteins called porins, which form channels and let material diffuse from one side of the membrane structure to another. The inner membrane contains around a fifth of the total protein in the mitochondrion structure. The inner membrane does not have porins, which helps makes it impenetrable to other molecules. Along with this, the inner membrane has a phospholipid called cardiolipin which adds another layer of protection to make it even harder for anything to enter the structure that should not be there.

  • Q:

    What is ATP and what is its role in the cell?

    A:

    Adenosine triphosphate, or ATP, is the energy currency of life, the way that individual cells store and use chemical energy. Any food or other source of energy a cell takes in is converted to ATP, in which form the mechanisms of the cell can easily use it. It does this by shedding a phosphate group, becoming adenosine diphosphate, or ADP, a highly energetic reaction that powers all of a cell's molecular machinery.

  • Q:

    What organelle produces ATP?

    A:

    The mitochondria inside a cell produces ATP, or adenosine triphosphate. Cellular respiration is responsible for ATP production, a process in which ATP production occurs after biochemical energy from nutrients is converted.

  • Q:

    What is a compound that provides energy for cells to do their work?

    A:

    Adenosine triphosphate, or ATP, is one of the most important energy-providing compounds used by cells to maintain their metabolism. Often described as the "energy currency" of a cell, ATP is a nucleotide comprised of three phosphate groups, the sugar ribose and adenine. ATP is found within cell fluid in concentrations that range between 0.5 to 2.5 milligrams per milliliter.

  • Q:

    Where does ATP synthesis occur?

    A:

    Synthesis of the compound adenosine triphosphate, or ATP, occurs on the inner membranes of bacterial cells and on the mitochondria and chloroplasts of plant and animal cells. The mitochondria and chloroplasts are structures inside plant and animal cells that are surrounded by a membrane.
