short answer questions on cellular respiration


Each fraction was incubated with glucose or pyruvate. You are asked to be part of a team looking for life on the Moon. Cellular respiration in the absence of molecular oxygen is (a) photorespiration (b) glycolysis (c) EMP pathway (d) HMS pathway Answer: (b) glycolysis 2. Q. The respiratory quotient besides other factors, depends on the type of respiratory substrate (e.g., glucose) and the completeness of oxidation. Therefore, blocking oxidative phosphorylation effectively decreases ATP concentrations in the cell. It is a series of reactions in which 6 carbon glucose molecules converts into two 3 carbon molecules of pyruvic acid. It produces 4 molecules of ATP. Click to rate this post! Tests were carried out during incubation for the presence of either carbon dioxide or lactic acid. All questions focus on specific parts of the respiration process. In the presence of enzyme pyruvate decarboxylase and TPP (thiamine pyrophosphate), pyruvate is broken down to form acetaldehyde releasing carbon dioxide. Answer: Fermentation is defined as the anaerobic breakdown of carbohydrates and other organic compounds into alcohols, organic acids, gases etc., with the help of microorganisms or their enzymes. In this cellular respiration worksheet, high schoolers answer 34 questions in a variety of types including fill in the blank, short answer and matching. Certain bacteria can remain alive in food canned in air-tight but improperly prepared containers. fun stuff with fun people that's really lame. Cellular respiration is the name given to a series of biochemical reactions that: makes glucose from carbon dioxide and water uses glucose to make ATP uses glucose to make oxygen There are bacteria and fungi that, in the absence of oxygen, use their anaerobic metabolic capability for energy supply. The enzyme ATP synthase is considered to be the 5th complex of electron transport chain. Let us know about it through the REPORT button at the bottom of the page. This happens by cells breaking down glucose into carbon dioxide (which we breath out) and water. (b): Glycolysis is the biochemical change in which one molecule of glucose is […] The overall reaction is broken into many smaller ones when it occurs in the body, most of which are redox reactions themselves. … The link between glycolysis and citric acid cycle is. What is cellular respiration? Research papers on cyber security 2020. ... Answer: Anaerobic respiration is similar to aerobic respiration in that it uses an electron transport chain with something other than oxygen as the terminal electron receptor. Chemical equation for cellular respiration. [Total: 8 Average: 3.9] Cellular respiration is a set of metabolic reactions and processes that take … Cellular Respiration Quiz: Learn and Practice for Free Read More » Although technically, cellular respiration is a combustion reaction, it clearly does not resemble one when it occurs in a living cell. This happens by cells breaking down glucose into … Respiration in Organisms Class 7 Science Extra Questions Short Answer Type Questions. The two common products are ethyl alcohol and lactic acid. RQ=Volume of CO2 release/volume of oxygen absorbed. Answer: It takes place in the cells of organisms. Answer: The sequence of reactions which converts glucose into pyruvic acid with the production of ATP is termed as glycolysis. Answer: Krebs cycle is a cyclic pathway whereas glycolysis is a linear pathway. Cellular respiration is considered an exothermic redox reaction. Cell Respiration Answers Answer: The metabolism "of choice" would probably be anaerobic respiration. PLAY. The electron transport continues to function, leading to oxygen consumption but phosphorylation of ADP is inhibited. Learn vocabulary, terms, and more with flashcards, games, and other study tools. answer choices Cellular Respiration Photosynthesis Aerobic Anaerobic Tags: Question 3 SURVEY 30 seconds Q. Connections between cellular respiration and other pathways (Opens a modal) ... Fermentation and anaerobic respiration Get 3 of 4 questions to level up! Ans: The series of oxidation reduction reactions in which substances (glucose) are oxidized to carbon dioxide and oxygen and energy is released is called respiration. Metabolic reactions that use the energy from carbohydrate, fatty acid, or amino acid breakdown to produce ATP molecules. Cellular Respiration Short Questions and Answers One mark questions with answers 1. cellular-respiration-guide-answer-key 2/5 Downloaded from web4.1418now.org.uk on January 8, 2021 by guest Modules-McDougal Littell Incorporated 2005-01-01 Instructor's Manual and Study Guide Answers for the Human Body in Question 1. Krebs cycle occurs inside mitochondria whereas glycolysis occurs inside cytoplasm. Most of the energy released in combustion is lost in the form of heat. someone give me a short, 1 or 2 sentence answer to this science question about cellular respiration?
