Read all of Part I: â€Å"Macronutrients and Energy†. When you are finished, answer the following questions: a) First, find out what nutrients Janine and Mitchell are talking about. Using a biology textbook and the resources listed, describe what the following molecules are and what they are used for in the human body. List some specific examples of each. Also list major dietary sources of each. a. Proteins b. Carbohydrates c. Fats b) Janine made this statement: â€Å"†¦ if your brain doesn’t get carbs—well, glucose, anyway—you get†¦show more content†¦d) Janine said that increasing muscle mass increases metabolism. Is she right? If so, how does this work? If not, why not? Check a biology textbook for information on the structure of muscle cells for clues. e) Mitchell said that the herbal product â€Å"detoxifies† the body. Janine said it’s a diuretic. Find out what a diuretic is and what effect it has on the body. f) What body systems remove toxins from the body? What are â€Å"toxins,† and where do they come from? Do toxins really cause you to gain body fat or prevent you from losing weight? g) Body image and dieting go hand-in-hand. When body image is distorted, people can diet to excess. Do you think that Mitchell has a body image problem? What further health problems can result from a body image problem? 4. When you are finished, go on to Part III: â€Å"Hormones and Homeostasis†. Read the passage and answer the following questions: a) What is meant by â€Å"sugar†? What is a â€Å"carbohydrate†? How are sugars and carbohydrates related? b) Janine mentioned blood sugar levels, which puzzled Mitchell. What does blood have to do with sugar? How do endocrine hormones control blood sugar levels? Why is the homeostasis of sugar balance important for overall body health? Include a brief discussion of diabetes and hypoglycemia in your answer. c) What other hormones could affect Mitchell’s appetite? Where do these hormones originate, and what are their effects?

(Biology-online.org, 2008) Metabolic pathways consist of two phases, a releasing energy and a storing energy phase. The phase that releases energy is catabolism and the phase which stores energy is anabolism. (Biocab.org, 2007). Catabolic reactions are exergonicRead MoreBiology : Evolution, Energy, Information, And Systems1436 Words   |  6 PagesBiology, the study of life and living organisms, is complex and encompasses a multitude of theories and ideas. In AP Biology, the fourth unit covered was genetics. Chapters 11, 12, 13, 14, 15, 16, and 18 in the textbook, Campbell’s Biology in Focus, not only discusses the four main ideas of biology: evolution, energy, information, and systems, but it also gives examples of each in order to help guide the reader’s understanding of the concepts. The first big idea of AP Biology is: â€Å"the processRead MoreEssay on Human Development Shaped by Biology and Experience1036 Words   |  5 PagesHUMAN DEVELOPMENT SHAPED BY BIOLOGY AND EXPERIENCE The first core concept suggested by From Neurons to Neighborhoods depicts human development forming from the interplay of an individual’s biology and experience. Early scientists in this particular field created testable hypotheses to understand the dynamic interaction between the nature-nurture phenomenon. For example, some scientists such as Arnold Gesell considered emerging skills to be the product of an individual’s genetic make-up, while othersRead MoreSenior Secondary Mastering Biology Textbook Answers5629 Words   |  23 PagesNew Senior Secondary Mastering Biology Textbook answer Book 1A p.1/23 Suggested answers to Exercise and Reading to learn (Note: The overseas examination boards bear no responsibilities for the suggested answers contained in this publication.

In both guys and females, FSH animates gamete generation and LH invigorates creation of hormones by the gonads. I don’t think we would be able to survive without the Endocrine system because the endocrine system is what regulates out metabolism, reproduction, sleep, tissue function, and reproduction. We would not be able to survive if our bodies were not in balance at all times nor reproduce in order to continue our species. Sources †¢ Hormones. (n.d.).

Rough ER is composed of a large but convoluted flattened sac. The main function of the smooth ER is the production of lipids and the metabolism of compounds (such as the breakdown of glycogen into glucose). Because of the different functions between the rough and smooth ER, different specialised cells will have different amounts of each; for example, hepatic cells have large amounts ofRead MoreE Coli And Its Effects On The Environment1442 Words   |  6 Pagesspiral or cocco), Gram-positive, fermentative, facultative anaerobic or microaerophilic organotrophs. They form chains. L. Bacillus produce lactic acid through the fermentation of glucose, lactose, and sugars. The process is called homofermentative metab olism (Siegrist 2017). Lactobacillus is a beneficial bacteria that is found in the body, especially the small intestine, vagina, and mouth.
