The majority of ATP in aerobic, eukaryotic cells is produced by the mitochondria.
In this regard, what part of the cell is ATP produced in?
Glycolysis – begins glucose metabolism in all cells to produce 2 molecules of pyruvate. Occurs outside of mitochondria, usually in cytoplasm. Cellular Respiration – uses oxygen from the environment and converts each pyruvate to three molecules of carbon dioxide while trapping the energy released in this process in ATP.
Which organelle produces ATP for the cell?
Most eukaryotic cells contain many mitochondria, which occupy up to 25 percent of the volume of the cytoplasm. These complex organelles, the main sites of ATP production during aerobic metabolism, are among the largest organelles, generally exceeded in size only by the nucleus, vacuoles, and chloroplasts.
Where does the ATP store energy?
The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
How is ATP used to provide energy?
Energy is usually liberated from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate-oxygen groups, leaving adenosine diphosphate (ADP). When the ATP converts to ADP, the ATP is said to be spent.
Where does the majority of ATP synthesis occur?
The overall process of creating energy in this fashion is termed oxidative phosphorylation. The same process takes place in the mitochondria, where ATP synthase is located in the inner mitochondrial membrane and the F1-part projects into mitochondrial matrix.
Do chloroplasts produce ATP energy?
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
How does ATP synthase produce the energy to make ATP?
H+ ions pass through ATP synthase from the thylakoid space into the stroma causing ATP synthase to spin, releasing energy. The energy is picked up by ADP and a phosphate forming ATP. light is absorbed increasing the energy of the electrons. the electrons are passed down the electron transport chain.
How does the ATP synthase work?
ATP Synthase: A Molecular Motor. Its function is to convert the energy of protons (H+) moving down their concentration gradient into the synthesis of ATP. 3 to 4 protons moving through this machine is enough to convert a molecule of ADP and Pi (inorganic phosphate) into a molecule of ATP.
What organelle makes protein for use outside the cell?

When ATP is broken down in a chemical reaction what is released?
Bonds are formed between water and phosphate. Here is a good link: Bonds are both broken and made in chemical reactions but many biology teachers and textbooks state that “Breaking ATP bonds releases energy.” In reactions bonds are broken and made.
Which organelle makes protein for use outside the cell?
The rough endoplasmic reticulum is where most protein synthesis occurs in the cell. The function of the smooth endoplasmic reticulum is to synthesize lipids in the cell. The smooth ER also helps in the detoxification of harmful substances in the cell. Ribosomes- Organelles that help in the synthesis of proteins.
Why do we need ATP when we already have glucose?
Carbohydrate loading is a strategy used by endurance athletes to maximize the storage of energy, in the form of glycogen, in the muscles. Glycogen forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose, which is then turned into ATP through the process of cellular respiration.
What other cellular structures organelles can produce ATP?
In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes. Each of these organelles performs a specific function critical to the cell’s survival.
What is the function of mitochondria in cells?
Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.
What are the three parts of ATP?
Its Structure. The ATP molecule is composed of three components. At the centre is a sugar molecule, ribose (the same sugar that forms the basis of RNA). Attached to one side of this is a base (a group consisting of linked rings of carbon and nitrogen atoms); in this case the base is adenine.
How does a cell get its energy from ATP?
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Where are sugars produced in a plant?
Sugar is made through photosynthesis by a chemical reaction within the plant’s cell. Photosynthesis takes place in the chloroplast of a cell. Light is absorbed into the cell by chlorophyll which is located in the chloroplast (an organelle in a plant cell.).
Where is the location of ATP synthase?
In mitochondria ATP synthase is located in the inner membrane, the hydrophilic catalytic F1 portion is sticking into matrix. In a way a mitochondrion is a bacterium “swallowed” by the eukaryotic cell: then the inner mitochondrial membrane corresponds to the bacterial cell membrane.
What cell structure is used for protein synthesis?

Where is the cell wall located?
A cell wall is a layer located outside the cell membrane found in plants, fungi, bacteria, algae, and archaea. A peptidoglycan cell wall composed of disaccharides and amino acids gives bacteria structural support.
Which organelle makes glucose for the cell?
Cell Organelle PicturesABCell Membrane,Allows materials to move in and out of cells.Cytoplasm,Gelatinelike substance, holds all cell organelles.Chloroplast,Green organelle, makes glucose from sunlight, water, and carbon dioxideLarge Vacuole,Plant Cell – stores food, starch, water, and waste.
What is ATP and what is it used for?
Adenosine triphosphate (ATP) is a nucleotide used in cells as a coenzyme. It is often called the “molecular unit of currency”: ATP transports chemical energy within cells for metabolism.
