Biology Cellular Respiration Quiz

Calorie the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius
Cellular Respiration the process that releases energy from food in the presence of oxygen
Aerobic pathways of cellular respiration that require oxygen
Anaerobic pathways of cellular respiration that do not require oxygen
Fermentation a process by which energy can be released from food molecules in the absence of oxygen
Food ______ provides living things with the chemical building blocks they need to grow and reproduce because food molecules contain chemical energy that is released when its chemical bonds are broken.
Energy ________ stored in food is expressed in units of calories.
Cells ________ use all sorts of molecules for food, including fats, proteins, and carbohydrates and the energy stored in each of these molecules vary because their chemical structures, and therefore their energy-stored bonds differ.
Cells _______ break down food molecules gradually and use the energy stored in the chemical bonds to produce compounds such as ATP that power the activities of the cell.
6O2 + C6H12O6 --> 6H2O+ ATP What is the Cellular Respiration Equation?
cellular respiration The three main stages of __________ _______________ are glycolysis, the Krebs cycle, and the electron transport chain.
Glycolysis ____________ produces only a small amount of energy and most of glucose's energy (90%) remains locked in the chemical bonds of pyruvic acid at the end of glycolysis.
Krebs During the ________ cycle, a little more energy than in glycolysis is generated from pyruvic acid.
oxygen The electron transport chain produces the bulk of the energy in cellular respiration by using ________, a powerful electron acceptor.
mitochondria The Krebs cycle and electron transport chain are both aerobic processes which take place inside _______________.
Glycolysis ___________ is an aerobic process that does not directly require oxygen which takes place in the cytoplasm of a cell.
oxygen In the presence of _________, the complete breakdown of glucose through cellular respiration results in the production of 36 ATP molecules.
Photosynthesis _____________ removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
Photosynthesis ______________ releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.
deposits; withdraws The energy flows in opposite directions, photosynthesis _________ energy, and cellular respiration _________ energy.
energy The release of ________ by cellular respiration takes place in plants, animals, fungi, protists, and most bacteria but energy capture by photosynthesis occurs only in plants, algae, and some bacteria.
Fermentation _______________ occurs in the cytoplasm of cells.
anaerobic Under ___________ conditions cells convert NADH produced by glycolysis back into the electron carrier NAD+, which allows glycolysis to continue producing ATP.
lactic Most organisms, including humans, carry out fermentation using a chemical reaction that converts pyruvic acid to _______ acid.
C3H6O3 + NADH --> C3H6O3 + NAD+ What is the Fermentation equation?
lactic acid fermentation For short, quick bursts of energy, the body uses ATP already in muscles as well as ATP made by _______ _____ ____________.
Lactic acid fermentation _______ ______ _____________ can supply enough ATP to last 90 seconds however; extra oxygen, is required to get rid of the lactic acid produced.
Fermentation _____________ is not the first choice of energy because it doesn't release as much and there is more waste products produced.
Cellular respiration _________ ___________ releases energy more slowly than fermentation does.
carbohydrate glycogen The body stores energy in the form of the ____________ __________ which last for 15 to 20 minutes of activity. After that, the body begins to break down other stored molecules, including fats, for energy.
