What organelle is responsible for RNA synthesis?

What organelle is responsible for RNA synthesis?

Ribosomes

Which cellular organelle is responsible for transcription in the cell?

For creating proteins there is a special organelle in the cell called the ribosome. The ribosome is found in the cytoplasm of the cell. However, the genetic code on the DNA is contained in the nucleus, which is in a different part of the cell.

Which organelle is most closely associated with cellular respiration?

mitochondria

Which two organelles are most closely associated with the Endosymbiotic theory?

The endosymbiotic origin of mitochondria and chloroplasts is widely believed because of the many similarities between prokaryotes and these organelles: 1. Mitochondria and chloroplasts are similar in size and shape to prokaryotes. 2.

What is the evidence of Endosymbiotic theory?

The evidence suggests that these chloroplast organelles were also once free-living bacteria. The endosymbiotic event that generated mitochondria must have happened early in the history of eukaryotes, because all eukaryotes have them.

What are the structural similarities and differences of chloroplast and mitochondria?

Both the chloroplast and the mitochondrion are organelles found in the cells of plants, but only mitochondria are found in animal cells. The function of chloroplasts and mitochondria is to generate energy for the cells in which they live. The structure of both organelle types includes an inner and an outer membrane

What are the two similarities between mitochondria and plastids?

Solution : (i) Both are double-membrane bound organelles. (ii) Both are capaable of producing some of their own proteins due to possession of DNA, RNA, Ribosomes and enzymes.

What do mitochondria do?

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 process produces the greatest amount of ATP?

The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.

What happens if you inhibit ATP synthase?

Inhibition of the ATP synthase compromises the output of ATP by OXPHOS and rewires energy metabolism to an enhanced glycolysis

Which process occurs when oxygen is not available quizlet?

In the absence of oxygen, a cell will go through anaerobic respiration and a process called fermentation. Occurs in yeast when oxygen is not available. If oxygen is NOT present, then the cell will go through the process of anaerobic respiration, commonly fermentation, in order to obtain energy. You get less ATP.

Why is oxygen important to blood and to the cells quizlet?

Blood, carried throughout the body’s circulatory system, transports food to cells in a form they can use. Why is oxygen important to blood and to the cells? Oxygen is necessary for cell growth and energy. Oxygen enters a persons bloodstream through the lungs.

What are the three main functions of blood?

Blood has many different functions, including:

  • transporting oxygen and nutrients to the lungs and tissues.
  • forming blood clots to prevent excess blood loss.
  • carrying cells and antibodies that fight infection.
  • bringing waste products to the kidneys and liver, which filter and clean the blood.
  • regulating body temperature.

Why is oxygen important to blood and to the south?

In cellular respiration, oxygen is required to break down the complex organic substances (like glucose) obtained from food through digestion, in order to release the energy present in them. This energy is stored in the form of ATP and used whenever needed by the body for carrying out the various life processes

Why is human heart called a double pump?

Your heart is a single organ, but it acts as a double pump. The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. It then delivers oxygen-rich blood back to your heart. The second pump delivers oxygen-rich blood to every part of your body.
