Life Science Cells Are Us Meeting Cells Energy Needs Post-Test
Which of the following best describes the role of the respiratory system in cellular respiration? A. It brings carbon dioxide into the body for use in photosynthesis B.It expels oxygen from the body which is a waste product of cellular respiration C. It brings oxygen into the body which is a reactant in cellular respiration and removes carbon dioxide which is a waste product D. It removes carbon dioxide which is a reactant in cellular respiration and brings in oxygen which is a waste product
Which of the following best describes the structure of mitochondria? A. A sac of enzymes enclosed by a single membrane B. A membrane surrounding folds of other membranes C. A small two piece structure composed of protein and RNA D. A sac of DNA enclosed by a porous membrane
Which of the following organ systems has the most similar function to mitochondria of breaking down nutrients from foodstuffs into usable units of energy? A. Nervous system B.Endocrine system C. Digestive system D. Excretory system
Which of the following best describes the function of proteins in cellular respiration? A. They can be transformed into lipids which are the most usable form of energy B. They make up enzymes which aid in the reactions of cellular respiration C. They direct cellular activity D. The end product of cellular respiration is a protein
Which of the following most accurately describes cellular respiration? A. Water and oxygen are combined to form hydrogen peroxide B. Glucose and oxygen are broken down to form water, carbon dioxide, and ATP C. UV light powers the combination of water and carbon dioxide to form glucose and oxygen gas D. Lipids and oxygen are combined to form glucose
