Cellular Respiration Short Questions and Answers One mark questions with answers 1. The energy a cell needs to build molecules or power cellular respiration is supplied by. The energy a cell needs to build molecules or power cellular respiration is supplied by. Aerobic cellular respiration is a part of cellular respiration, and it plays an important role in producing the energy that is required for various functions of a cell. Cellular Respiration Equation: Every machine needs specific parts and fuel in order to function. Cellular respiration is the process through which cells convert sugars into energy. Every cellular activity depends on energy, and food is the source of energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a … Cellular Respiration Process. Both eukaryotic and prokaryotic cells undergo cellular respiration. All organisms are made up of tiny cells which carry out various functions. Tags: Question 8 . Likewise, “biological machines” also require well engineered parts and good energy source in order to work.Perhaps the second most important molecule (DNA is the first) is adenosine triphosphate (also known as ATP).Basically, ATP serves as the main energy currency of the cell. The citric acid cycle initiates with (a) succinic acid (b) pyruvic acid (c) acetyl coenzyme A (d) fumaric acid Answer: (c) acetyl coenzyme A 3. Most biochemists agree that in prokaryotic microorganisms, a total of 36 molecules of ATP can be produced during cellular respiration. Carbon Dioxide is required to produce ATP. Preview this quiz on Quizizz. Cellular respiration in the absence of molecular oxygen is (a) photorespiration (b) glycolysis (c) EMP pathway (d) HMS pathway Answer: (b) glycolysis 2. This observation will allow your students to link the energy requirements of their bodies to the cellular respiration rate. Preview; Assign Practice; Preview. Practice. % Progress . Although cellular respiration involves many chemical reactions, the process can be summed up with the following simplified reaction: C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O + Chemical Energy … Cells can store the extracted energy in the form of ATP (adenosine triphosphate). Cell Energy (Photosynthesis and Respiration) Notes I. Explains molecular processes cells use to make energy in the presence of oxygen. The total energy yield is 36 to 38 molecules of ATP. Energy is the driving force of any work. In these particles, the energy of the protons is used to generate ATP, using ADP and phosphate ions as the starting points. Because oxygen is required for cellular respiration, it is an aerobic process. ... and water \(\ce{H_2O}\), releasing energy in the process. This indicates how strong in your memory this concept is. MEMORY METER. Cellular respiration is the process responsible for converting chemical energy, and the reactants/products involved in cellular respiration are oxygen, glucose (sugar), carbon dioxide, and water. Prep Work (15 minutes) While the exact steps involved in cellular respiration may vary from species to species, all living organisms perform some type of cellular respiration. Progress % Practice Now. Increasing the cellular respiration rate through exercise will result in higher amounts of carbon dioxide in their breath, which makes the indicator change color faster. SURVEY . Energy –ability to do work; forms of energy: heat, light, chemical, electrical, mechanical, kinetic, potential A. The cellular respiration process occurs in eukaryotic cells in a series of four steps: glycolysis, the bridge (transition) reaction, the Krebs cycle and the electron transport chain. Cellular Respiration Definition. Cells do cellular respiration to extract energy from the bonds of glucose and other food molecules. In cells, cellular respiration is the pathway of yielding energy in the form of adenosine triphosphate (ATP).
