In our bodies, how do oxygen and nutrients flow? Describe the functions of each organ system and how they are interconnected.
What is the process through which animals and plants transform food into energy?
Step by step
Solved in 2 steps
- Your classmates are discussing what happens during cellular respiration. Whose statement most accurately describes the process? (a) Nate: Molecules in our food react with oxygen and break apart, releasing energy, and then reform as different molecules (b) Ethan: Oxygen and food mix together, and our bodies use that mixture for energy (c) Kim: Oxygen comes in through our lungs, and then transforms into carbon dioxide before it goes back out (d) Imani: Oxygen and molecules from our food cause a chemical reaction, and some of the atoms recombine to form energyHow do both activation energy barriers and enzymes help maintain thestructural and metabolic order of life?When you exercise, your body depletes oxygen faster. As a result, respiration and depth of breathing increases to take in more oxygen. In addition, your heart rate increases to speed up the delivery of oxygen to your muscles that are exercising. What type of homeostatic mechanism does this represent? a) Positive feedbackb) Negative feedbackc) Feedforward
- Compare the body systems in a plant and an animal when relating to a) transporting materials around an organism b) nutrition. Make sure to list which tissues, organs and body systems are involved for each processHow does the knowledge of cellular processes help make us personal choices about exercise and diet?How circulatory system maintains glucose in our blood?
- On the very first page of this tutorial, we talked about the circulatory and respiratory systems being related. Now we're going to combine these into one process. Instead of following oxygen going into the body, we are going to trace the route that carbon dioxide takes on its way out of the body. The carbon dioxide is produced in the cell during cellular respiration. Starting at the organelle where this process takes place, find the route a molecule takes from the cell to the heart. right atrium vena cava 3 | interstitial fluid cytoplasm of cell 5 | right ventricle 6 vein 7 | capillary 8 E mitochondria :::: 4.Read the following statements: ANIMAL AND PLANT PHYSIOLOGY Both plant biologists and animal biologists seek to understand how their focal organisms have evolved to interact with the environment. Despite this similarity in goals, the differing biology of plants and animals as well as other factors have led these scientific communities to diverge. Scientific discoveries that have occurred in each community in relative isolation may advance progress in the other community and set the stage for broad scientific syntheses. Integrative and Comparative Biology, Volume 42, Issue 3, July 2002, Pages 409-414, https://doi.org/10.1093/icb/42.3.409 Environmental stress can be either natural or anthropogenic (i.e., resulting from human actions) in origin. Many environmental stresses, such as most hurricanes, droughts, floods, and fires are a periodic feature of life on Earth. In contrast, environmental stresses such as the production and release of new chemical compounds and large-scale land-use…Which of the statements about the use of chemical energy for biological functions is INCORRECT? A) Some chemical energy is used for metabolic maintenance B)Some chemical energy is used to manufacture molecular and cellular components C) Some chemical energy is irreversibly lost in the form of heat D) All manufactured molecular and cellular components are kept by the animal itself E) The three major types of physiological work done are biosynthesis, maintenance, and external work
- Please construct a model to show that the digestive, respiratory, and circulatory systems work together to supply the body cells with the glucose and oxygen needed for aerobic cellular respiration. Feel free to use words, diagrams, arrows, flowcharts, etc. to get your ideas across. Make sure you include the following information: Digestion of starch into glucose and the location(s) of digestion. Absorption of glucose into the blood and the location of absorption. Blood transporting glucose from the absorption site to the tissues. Glucose entering the tissue cells from the blood. O2 entering the blood in the lungs and the specific location of entrance in the lungs. Blood transporting O2 from the lungs into the tissues. O2 enters the tissues from the blood.Describe the relationship between the organ systems of the human body and the individual needs of each human cell to undergo cellular respiration and maintain homeostasisHow Is Metabolism Integrated in a MulticellularOrganism?
