Definition Of Mitochondria: Structure, Features, Functions, Images, Symptoms

Definition mitochondria They are – Structure, Characteristics, Functions, Images, Roles and Abnormalities for Plants and Animal Cells – Well, this time it’s more playful. will present in detail a Paper About Mitochondria.

However, at the previous meeting, quipper also delivered material on a Fund Balance Generator Application The fastest. Alright, to round out what the topic of discussion is this time, let’s take a look at the full breakdown below.

Definition of Mitochondria

Definition Of Mitochondria
Definition of Mitochondria

In Biology, there are many lessons that we must understand, starting with the parts that are largest and visible to the eyes to the smallest parts and invisible to the eyes.

In a general sense, mitochondria are also explained as a single-cell organelle that functions as a breathing site in humans, animals, and plants.

For example, when the processCalcium homeostasis metabolism, fatty acids, cell tissue transduction, pyrimidine biosynthesis and protein processing can be used as energyI.

The cell organelles of mitochondria are also known to play a role in the death of certain cells in the body’s tissues.

For example, once in the tissue of the body there is a cellular process that becomes abnormal or diseased, the mitochondria will be selected by the abnormal cellular organisms so that they cannot develop in the tissue of the body.

Therefore, with the presence of mitochondria in the bodies of living beings, for example, in humans, animals, plants, the functions of vital organs in the bodies of living beings can function correctly.

Structure of mitochondria

As cell organelles, mitochondria have several structures that can be divided into 5 (five) namely.

  • Inner Membrane
  • membrane outside
  • Krista
  • Space between Membranes
  • Headquarters

1. External Membrane

Outer membrane, has milk and effectPhospholipid Bilayerwhich is like Spermeable emijust as there is contentporine protein.

In this layer can be passed Permeable with ions, adenosine triphosphate, adenosine diphosphate & Nutrient Molecules.

Occupation outer membrane: It is explained that this part of the outer membrane contains enzymes that work in assisting the biosynthesis process in the body tissues of living beings.

2. Internal Membrane

The inner membrane is a complex membrane, but this permeable membrane is formed by complex molecules and electron transport, ATP complexes and transport proteins.

Inner Membrane Function: It serves to help manufacture an energy in the tissues of the body of living beings.

3. Krista

A crest is a fold in the inner membrane of the mitochondria.

Crystal Function: These cristae work by helping to expand the structure of the membrane that is inside the cell as mitochondrial DNA molecules develop further and further.

4. Intermembrane Space

The intermembrane space is the space between the outer and inner membranes. The intermembrane space is largely responsible for oxidative phosphorylation.

Uses of the space between cell membranes that is, for the process where an important reaction takes place in a cell.

5. Matrix

The matrix containing DNA molecules is responsible for cellular respiration, enzymes are responsible for the citric acid reaction cycle, these gases are dissolved as oxygen, carbon dioxide and water.

Array Function:It only stores the important parts like genetic material, DNA, ribosomes and other important ions.

Explain the role of mitochondria

The primary function of mitochondria is cellular respiration.

Cellular respiration is a chemical process that works to release stored energy in the body.Glucose.

The energy used in breaking down a glucose is provided by ATP molecules.

And ATP molecules are produced by the organelle itself. The entire breathing processCell Aerobesconsists of 3 steps as below:

1. Glycolysis

Glycolysis actually means “glucose breakdown“Glycolysis is an important process for cellular respiration itself.

As for glucose which has 6 carbon atoms. Enzymes found in the cytosol work to oxidize glucose molecules into 2 molecules, each with 3 carbon atoms.

Glycolysis produces 2 molecules of ATP, that is, 2 molecules of pyruvic acid and 2 molecules of NADH.Nicotinamide Adenine Dinucleotide).

2. Siklus Krebs(Citric acid cycle)

Before the krebs cycle works, that’s why it’s done Oxidative Decarboxylationthe pyruvic acid molecules produced in glycolysis will be converted toKoenzim-A asetil,which will be used in the krebs cycle.

The krebs cycle will oxidize acetyl-CoA to carbon dioxide, and from this process it can also produce 3 molecules of NADH and 1 molecule of FADH2.

3. Electron Transport Chain

The electron transport chain consists of an electron transporting portion of the mitochondrial membrane of the krebs cycle (NADH & FADH2).

ATP molecules are produced by a redox reaction of NADH and FADH2. Eukaryotic cells produced about 36 ATP after performing cellular respiration.

Other functions of the Mitrochondria:

  • Cell signaling to a neuron.
  • Managing apoptosis.
  • Controls the cell cycle.
  • Monitor differentiation, cell development

The benefits of mitochondria in the body of living beings

Mitochondria play a very important role in the body of living beings, including:

  • Produce cellular energy so that it can be used by the body’s metabolic system.
  • Carbohydrate metabolism that takes place in mitochondria will be oxidized by water, carbon dioxide and oxygen.
  • The energy that was produced by the mitochondria is in the form of 30 molecules, made for each glucose molecule.
  • In each glucose it can produce 2 molecules.
  • Mitochondria function to manage the metabolic activities of cells.
  • The mitochondrial function is to be able to break down foods that can provide energy, for example: carbohydrates, fats, proteins and others.
  • Mitochondria function to receive the results of enzymes that have been carried out in steps with a continuation, after which the process is carried out again to become molecules with certain capacities. These molecules can mix oxygen so that it can be properly distributed to the blood vessels and the results are positive.
  • It serves to maintain the concentration of calcium ions, for bone density and all kinds of cell parts.
  • Mitochondria can help cells that have managed to perform this function and provide space to store calcium ions.
  • Mitochondria work in a process that kills certain cells that are naturally programmed in the body. For example, abnormal cells or diseased cells, toxic cells, will be killed in large numbers. And when a metabolic process is underway, these abnormal cells cannot reproduce later.
  • Facilitate the process of organ functioning to function optimally, so when mitochondria can no longer function or undergo abnormal cell death, it can affect the performance of these organs.

Mitochondria is a type of cellular organelle that has the function of site for the function of cellular respiration to occur for living beings, but in addition, there are many cellular uses such as fatty acid metabolism, calcium homeostasis, cellular signal transduction, pyrimidine biosynthesis, and also to serve as an energy conductor if it is in the form of adenosine triphosphate which is in the catabolic pathway.

What is the function of mitochondria?

No mitochondrial function the main thing is to be able to produce an energy that will later be obtained from the process of cellular respiration, but mitochondria also have occupation as a regulator of activity in cellular metabolism

Now this is what can convey about the meaning of mitochondria, I hope that what has been conveyed above can be useful to you all.
