1/10/2017 Molecular Biology Pretest Name: Class: Date: Question #1 Which organelle is responsible for cellular respiration? A) cell membrane B) cholorplast C) endoplasmic reticulum D) mitochondria Question #2 Which process produces oxygen? A) chemosynthesis B) osmosis C) photosynthesis D) respiration Question #3 Which statement correctly describes cellular respiration? A) Carbon dioxide plus sugar makes oxygen, energy, and water. B) Carbon dioxide plus water makes oxygen, sugar, and energy. C) Oxygen plus sugar makes carbon dioxide, energy, and water. D) Oxygen plus water makes carbon dioxide, sugar, and energy. Question #4 Which process produces carbon dioxide? A) chemosynthesis B) osmosis C) photosynthesis D) respiration Question #5 What is the most likely consequence of increased cellular respiration? A) more energy available to the cell B) increased oxygen released by the cell C) cell death D) decreased diffusion https://app.masteryconnect.com/materials/1149157/print 1/4 1/10/2017 Molecular Biology Pretest Question #6 The diagram shows a typical animal cell. Which numbered structure is most closely related to the process of energy production? A) 1 B) 2 C) 3 D) 4 Question #7 Why do all animals need to eat other organisms, but plants do not? A) Plants can make all of their own nutrients and sugar, but animals must get them from other organisms. B) Plants cannot move, but animals can, so plants must get their nutrients from the soil. C) Plants make their own sugar, but animals must get it from other organisms. D) Plant cells are simpler than animal cells, so they need fewer nutrients and are able to absorb them from the soil. Question #8 What do plants use to make food? A) water, light, oxygen B) carbon dioxide, water, oxygen C) carbon dioxide, light, soil D) water, light, carbon dioxide Question #9 Plants use carbon dioxide in photosynthesis to create energy in the form of sugars that the plant uses to function and oxygen which is released as a gas. What process uses those products as reactants, and where does it occur? A) osmosis; in the cell membrane B) cellular respiration; in the mitochondria C) Digestion; in the cytoplasm D) cellular reproduction; in the nucleus Question #10 A frog feeds on a grasshopper for food. How does the food provide energy to the frog? A) The food is broken down to release energy. B) The food is stored in the body to produce energy. C) The food combines with ATP to form energy molecules. D) The food releases carbon dioxide to produce energy molecules. https://app.masteryconnect.com/materials/1149157/print 2/4 1/10/2017 Molecular Biology Pretest Question #11 Which processes are responsible for cell growth and reproduction? A) mitosis and meiosis B) mitosis and osmosis C) meiosis and photosynthesis D) osmosis and photosynthesis Question #12 Which process occurring in plants provides energy to other organisms in the ecosystem? A) uptake of nutrients and minerals by plant roots B) storage of energy in the form of ATP molecules C) production of glucose and use of water and carbon dioxide D) oxidation of sugars to form carbon dioxide and water Question #13 Humans are multicellular organisms with organs that specialize in specific functions. Even though the organs and their cells have specific functions, all cells must perform certain processes. Which process would be completed by all human cells? A) fermentation B) meiosis C) photosynthesis D) respiration Question #14 Examine the process shown in the diagram. What is the purpose of this process in animal cells? A) energy production B) movement C) reproduction D) waste disposal https://app.masteryconnect.com/materials/1149157/print 3/4 1/10/2017 Molecular Biology Pretest Question #15 The organelle shown in the diagram is a mitochondria. This is where sugar is converted to energy inside a cell. What important compound given off during this process is missing? A) carbon dioxide B) carbon monoxide C) methane gas D) nitrogen gas https://app.masteryconnect.com/materials/1149157/print 4/4
