Which of the following statements best summarizes how the ATP cycle illustrated in the accompanying figure functions in cells? … They are exergonic and provide energy that can be used to produce ATP from ADP and Pi.
What is ATP and what is its role in a cell?
Explanation. Adenosine triphosphate (ATP) is a chemical compound which serves as the chemical fuel of living organisms. ATP is composed of adenine, ribose, and 3 phosphate groups. In plant cells, this compound is produced in mitochondria and chloroplasts.
How does ATP give energy?
Glucose can be converted into Glucose-6-phosphate by the addition of the phosphate group from ATP. ATP serves as the biological energy company, releasing energy for both anabolic and catabolic processes and being recharged by energy generated from other catabolic reactions.
How does ATP ADP cycle work?
ADP is continually converted to ATP by the addition of a phosphate during the process of cellular respiration. ATP carries much more energy than ADP. As the cell requires more energy, it uses energy from the breakdown of food molecules to attach a free phosphate group to an ADP molecule in order to make ATP.
How is ATP used in the body?
ATP is also involved in signal transduction – its phosphate groups are used up by kinases in phosphate transfer reactions which activate a cascade of protein kinase reactions. ATP plays a very important role in preserving the structure of the cell by helping the assembly of the cytoskeletal elements.
How does ATP power reactions quizlet?
ATP usually transfer energy to endergonic processes by phosphorylating (adding phosphates groups to) other molecules. (Exergonic processes phosphorylate ADP to regenerate ATP. A set of coupled reactions can transform the first combination into the second.
What is the role of ATP in the body quizlet?
what is the function of ATP? ATP transfers energy from the breakdown of molecules in food to cell processes.
Which of the following statements best summarizes how the ATP cycle illustrated in the accompanying figure functions in cells quizlet?
Which of the following statements best summarizes how the ATP cycle illustrated in the accompanying figure functions in cells? The cycle is used to regenerate ATP.
Which of the following statements best describes the relationship between the evolution of multicellular life on Earth and the laws of thermodynamics?
Which of the following statements best describes a relationship between the evolution of multicellular life on Earth and the laws of thermodynamics? Evolution has occurred in accordance with the laws of thermodynamics and resulted in an increase in the entropy of the universe.
What is ATP used for?
Adenosine triphosphate (ATP) is an organic compound and hydrotrope that provides energy to drive many processes in living cells, such as muscle contraction, nerve impulse propagation, condensate dissolution, and chemical synthesis.
How is ATP used?
ATP synthesized in mitochondria is the primary energy source for important biological functions, such as muscle contraction, nerve impulse transmission, and protein synthesis.
What is meant by an ATP cycle and why is it important in cells how does this involve ADP?
This cycle is used by cells as a means of converting the large amounts of energy in food molecules into the smaller amounts of energy needed to drive the synthetic reactions of celss, such as the formation of sucrose.
How energy is produced in the ATP cycle?
ATP is like a charged battery, while ADP is like a dead battery. ATP can be hydrolyzed to ADP and Pi by the addition of water, releasing energy. ADP can be "recharged" to form ATP by the addition of energy, combining with Pi in a process that releases a molecule of water.
How does ATP drive energy required reactions in the cell quizlet?
Hydrolysis of ATP produces a free phosphate group and a new molecule, adenosine diphosphate (ADP). That reaction releases energy. Its energy drives many chemical reactions within a cell. Cells can also make ATP from ADP by using energy to reconnect a phosphate group.
How does ATP perform work quizlet?
ATP is SYNTHESISED during reactions that RELEASE energy and it is HYDROLYSED to provide energy for reactions that require it. THE ADDITION OF A PHOSPHATE TO ADP TO FORM ATP USING ENERGY IN THE FORM OF SUNLIGHT. (It takes place in the chlorophyll-containing plant cells during photosynthesis).
Why is ATP important for a cell quizlet?
ATP stands for adenosine triphosphate. It is a molecule found in the cells of living organisms. It is said to be very important because it transports the energy necessary for all cellular metabolic activities.
What is ATP and why is it important to cells?
Adenosine Triphosphate (ATP) is the primary energy carrier in all living organisms on earth. Microorganisms capture and store energy metabolized from food and light sources in the form of ATP. When the cell requires energy, ATP is broken down through hydrolysis.
Which of the following is the most correct interpretation of the figure energy from catabolism can be used directly for performing cellular work?
Which of the following is the most correct interpretation of the figure? Energy from catabolism can be used directly for performing cellular work. ADP + Pi are a set of molecules that store energy for catabolism. ATP is a molecule that acts as an intermediary to store energy for cellular work.
Which of the following statements best summarizes an important consequence of the first law thermodynamics for living organisms?
Which of the following statements best summarizes an important consequence of the first law of thermodynamics for living organisms? Each organism ultimately must obtain all of the necessary energy for life from its environment.
Which of the following statements best describes how addition of a catalyst will affect a chemical reaction quizlet?
Which of the following statements best describes how addition of a catalyst will affect a chemical reaction? The catalyzed reaction will have the same ΔG as the uncatalyzed reaction.
What happens in the ATP cycle?
ATP collects small packets of energy from the food-burning power plants of the cell and transports this energy to where it is needed. Some energy in ATP is released to do work, such as move muscles or force a seedling out of the ground.
How can you explain the process of ATP ADP cycle?
- ADP is continually converted to ATP by the addition of a phosphate during the process of cellular respiration.
- ATP carries much more energy than ADP.
- As the cell requires more energy, it uses energy from the breakdown of food molecules to attach a free phosphate group to an ADP molecule in order to make ATP.
What is the function of ATP and why is it important?
ATP acts as a cell's storehouse of energy. It enables cells to store energy safely in small packets and release the energy for use only as and when needed. In other words, ATP serves to close the gap between energy-releasing reactions such as food breakdown and energy-requiring actions such as synthesis.
How do cells use ATP to drive endergonic reactions?
ATP donates its phosphate group to another molecule via phosphorylation. The phosphorylated molecule is at a higher-energy state and is less stable than its unphosphorylated form, and this added energy from phosphate allows the molecule to undergo its endergonic reaction.
What is ATP required for quizlet?
ATP is required for all life processes. Cells use ATP to help move molecules, ions, and other substances across their cell membranes.
How is ATP used to power other cellular reactions quizlet?
With the help of specific enzymes, the cell can use the energy released by ATP hydrolysis to drive chemical reactions that by themselves are endergonic. Coupled together the reactions are exergonic. This usually involves the transfer of a phosphate group from ATP to some other molecule such as the reactant.
What is ATP and why is it important in the cell?
Microorganisms capture and store energy metabolized from food and light sources in the form of ATP. When the cell requires energy, ATP is broken down through hydrolysis. The high energy bond is broken and a phosphoryl group is removed. The energy released from this process is used to drive various cellular processes.
