BioLab3 Cell Respiration Lab Report Name, date, course and section required for password: The lab report is unique each semester and checks have been put into place to ensure students are doing their own work. Copying from other students or from outside resources will result in a zero on the accompanying lab quiz. I. The ATP Cycle 1. Give an example: a. Autotroph b. Heterotroph 2. What is the main source of energy in plant and animal cells? 3. The energy in glucose cannot be used directly by cells and must be broken down into an intermediate smaller energy molecule called: 4.

Examine the chemical formula for starch breakdown. a. Which enzyme breaks down starch? b. Which enzyme breaks down maltose? 3. In Ex 1, view alcoholic fermentation at intervals of 20, 40, and 60 minutes, Record the volume of gas produced in each fermentation tube. Each tube is graduated in tenths of a ml. Read the amount of gas from the top, not the liquid level. Tube Solution 1 10% glucose + yeast 2 1% starch + yeast 3 1% starch + yeast + amylase © 2022 Access Learning Systems A SP22 Gas Volume (ml) 20 min. 40 min. 60 min. 1 a. Which tube had the greatest gas volume after 60 min? b. Which had the least volume after 60 min? Why? c. Why was amylase added in Tube 3? d. The gas released in this reaction was: III. Aerobic Respiration 1. What role does oxygen play in aerobic respiration? 2. How does the chemical formula for aerobic respiration differ from fermentation (anaerobic) formula? A. CO2 Production 3. In Ex 2, explain how carbonic acid is formed?

The indicator phenol red in the solution turned what color when a person exhaled into the solution? Why? 5. In the demonstration of 3 different respiratory bottles of beans, which produced CO2? B. Oxygen Consumption 6. In Ex 3, follow the steps and use the data collected to measure metabolic rate. 1. Mass of rodent (g): 2. Surface area of rodent in square meters (m 2): 3. Average time to consume 2 ml of oxygen from Table 7.3 (sec): 4. 5. 6. Oxygen consumption by the rodent (l/hr): Calculation = 2ml/45.67 multiplied by 3600/1000 Calculated oxygen consumption of the rodent (l/hr/m 2): Calculation = .1576/.0139 Calculated metabolic rate of rodent (Cal/hr/m2): Calculation = 11.34 X 4.8 7. Look at the table of metabolic rate of humans and compare which age and sex of a human compares most closely to a rodent. © 2022 Access Learning Systems A SP22 2 IV. Heat Balance and Human Metabolism 1. In Ex 4, record your height in inches, age, weight in pounds, and sex. Alternatively, you can take the measurements of a partner. height weight age sex 2. Calculate: a. Your BMR (Basal Metabolic Rate) or that of a partner. b. Using the same calculations, estimate BMR in 20 years. V. Factors That Determine Metabolic Rate 1. Using the flow chart list variables that affect Basal Metabolic Rate BMR Variables that increase BMR Variables that decrease BMR Summary Questions 1. Fill out the following chart comparing two pathways of energy in living organisms Type of Respiration Anaerobic Respiration (fermentation) Aerobic Respiration of Pyruvate after Glycolysis Is Oxygen involved? Where does this process occur? What products are produced?

Important information for writing discussion questions and participation

Welcome to class

Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires a lot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to

I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you.

Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted.

If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations.

Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements.

Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week.

I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!

Hi Class,

Please read through the following information on writing a Discussion question response and participation posts.
