adenosine triphosphate (ATP
In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.

What is the mitochondria function?

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).

Why are mitochondria called semi autonomous?

Complete answer: Mitochondria are regarded as semi-autonomous organelle please due to the presence of DNA (deoxyribonucleic acid), that can replicate independently and synthesize their proteins with ribosomes. Mitochondrial DNA is known as Mt- DNA and ribosomes are called mitoribosomes.

Why is mitochondria called powerhouse of the cell give three similarities and one difference between mitochondria and plastids?

Mitochondria is known as powerhouse of the cell because it creates energy for the cell. It releases energy in the form of ATP molecules. … Mitochondria is related to production of ATP molecules whereas plastids are the main site of photosynthesis.

What is the powerhouse of a cell quizlet?

contains nearly all the cell’s DNA and with it the coded instructions for making proteins and other important molecules.

Which organelle is the powerhouse of the cell and produces energy quizlet?

1) Mitochondria produce energy when food is broken down. They release energy for cell funtions. 2) They are often called the “powerhouse of the cell.”

How do mitochondria produce ATP energy for the cell?

Most ATP is produced in mitochondria through a series of reactions, known as the citric acid cycle or the Krebs cycle. … 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 does the mitochondria produce ATP?

Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration.

What is the energy molecule of the cell called answer key?

Adenosine triphosphate, or ATP, is the primary carrier of energy in cells. The water-mediated reaction known as hydrolysis releases energy from the chemical bonds in ATP to fuel cellular processes. adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things.

Why mitochondria is known as powerhouse of the cell class 9?

Mitochondria are known as the cell’s powerhouse because they are in charge of extracting energy from food via cellular respiration. The energy is released as adenosine triphosphate (ATP). It is an energy currency of the cell.

Where is energy produced in a cell?

mitochondria
In eucaryotes these reactions all take place in mitochondria, the organelle to which pyruvate and fatty acids are directed for acetyl CoA production (Figure 2-78). We should therefore not be surprised to discover that the mitochondrion is the place where most of the ATP is produced in animal cells.

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. … This means mitochondria are known as “the powerhouse of the cell”.

Why is the mitochondria the most important organelle?

As the power plants in virtually every human cell (as well as animal, plant, and fungi cells), mitochondria play an essential role in creating energy to drive cellular function and basically all of our biological processes.

Why it is called semi autonomous organelle in which form energy is produced in mitochondria?

Why mitochondria is called semi autonomous organelle? ???

It is the main site of producing energy by cellular respiration. … Mitochondria is called semi-autonomous organelles because they have their own genetic material (DNA) and are capable of synthesizing proteins required for their functioning.

Why mitochondria and plastids are called semi autonomous organelle?

Mitochondria and plastids have double membranes and own DNA. … They contain DNA as well as ribosomes and are able to synthesise some of its own proteins therefore, are called semi autonomous cell organelle.

Why are mitochondria and chloroplasts called as semi autonomous organelles?

Hint: Mitochondria and chloroplasts are called semi-autonomous cell organelles as they have their own DNA and ribosomes. Therefore, they can synthesize some of their proteins. For other proteins, they are dependent on the nucleus.

In which form is energy released from the mitochondria how it is utilized in the cell?

adenosine triphosphate (ATP)
Mitochondria: the energy converters

NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP). In ATP the energy is stored in the form of chemical bonds. These bonds can be opened and the energy redeemed.

What is the difference between mitochondria and mitochondria?

The only difference between mitochondria and mitochondrion is that mitochondrion is singular, and mitochondria is the plural form of the word.

What are the differences and similarities between mitochondria and plastids?

Plastids are similar to mitochondria in that they help in the production and storage of food (glucose). … The main difference between mitochondria and plastids is that mitochondria are found in all eukaryotic cells, but plastids are exclusive to plants and algae.

What makes up an ATP molecule quizlet?

ATP is made up of Ribose, adenine and three phosphate groups, therefore it is just like DNA and RNA with more phosphate. By the removal of one or more of the phosphate groups releases energy. … ATP provides energy to the cells to be used for: energy absorbing reactions (carb and protein synthesis).

What is the sugar that helps make up ATP?

ribose
ATP is composed of ribose, a five-carbon sugar, three phosphate groups, and adenine , a nitrogen-containing compound (also known as a nitrogenous base).

What is gastrin quizlet?

Gastrin is a hormone that was released in response to the rising pH in the stomach. Gastrin prods the stomach glands to produce protein digesting enzymes, pepsinogens, mucus, and HCl.

How did the mitochondria end up in the cell?

The endosymbiotic hypothesis for the origin of mitochondria (and chloroplasts) suggests that mitochondria are descended from specialized bacteria (probably purple nonsulfur bacteria) that somehow survived endocytosis by another species of prokaryote or some other cell type, and became incorporated into the cytoplasm.

Which of the following occurs in the mitochondria of a cell?

In general, cellular respiration can be divided into four stages: Glycolysis, which does not require oxygen and occurs in the mitochondria of all cells, and the three stages of aerobic respiration, all of which occur in mitochondria: the bridge (or transition) reaction, the Krebs cycle and the electron transport chain …

Why do cells need energy?

All living cells need energy to function in order for the chemical reactions occurring in the cells to take place. … The biochemical reactions, which take place in cells when a fuel substance such as carbohydrate (e.g. glucose or fructose) is broken down, will normally release more energy than they use.

What gives energy to the cell?

ATP, or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street. … During cellular respiration, glucose, in the presence of oxygen, is converted into carbon dioxide and water.
