Energy Enzymes Photosynthesis Respiration

Metabolism can be thought of a the many reactions that occur in cells which provide the energy that is necessary to keep organisms alive. The reactions that occur in cells can be grouped into two categories; either anabolic, those reactions that take small, low energy molecules and build them into larger, higher energy molecules or catabolic reactions, those reactions that take large, high energy molecules and break them down to release energy which is captured in the molecule ATP. This ATP can then be used to provide energy to other anabolic reactions in the cell that require energy. All of these reactions in the cell are facilitated by enzymes, proteins that speed up the rate of reactions.

The next series of videos will walk you through all of the steps that can be thought of as part of the various metabolic processes that occur in living things. The processes that are covered here are only a small number of those that exist in cells, but are the ones that are at the core of the life of cells

Genetics, Metabolism, Enzymes, Photosynthesis & Respiration

Instructions

You will have 70 minutes to complete the test from that time that you start it. You may use your study guides from the last two units on genetics and metabolism, and you may use your textbook. You may not use any other websites. If I see any indication that you have taken material from any website to answer test questions, I will receive a zero for the entire test.

Last Study Guide on Metabolism I highly recommend that you because there will definitely be test questions coming from it.

Pheochromocytoma

/in /by

Watch this video and do research and answer the questions below:

https://watch.liberty.edu/media/t/1_cl4younu

Cici Menza is a 54-year-old seamstress who started to experience what she thought were menopausal symptoms. She went to a physician and underwent a series of tests. The tests revealed the following:

Blood pressure was severely elevated at 195/105.

Heart rate was increased at 110 beats/min.

A positive 24-hour urinary vanillylmandelic acid (VMA) test that indicated pheochromocytoma (a rare tumor of the adrenal medulla).

A computed tomographic scan showing a 4-cm mass on her left adrenal gland.

1.Which hormones are secreted by a pheochromocytoma?

2.What are the two values reported for arterial pressure, and what is the significance of each value?

3.Why were both the systolic and diastolic blood pressures elevated?

4.Which adrenergic receptors contribute primarily to systolic blood pressure and which contribute primarily to diastolic blood pressure in this situation?

5.Why might you not prescribe propranolol initially to treat a pheochromocytoma?

Evolution Theory and Creation Science

/in /by

1) How should (or should not) evolution be taught in American high school biology classes? Should alternative ideas such as creation science or creationist views from other (>1) religions be presented? Give me your honest thoughts (no wrong answers) 100 words.

2) Name 5 important ideas/concepts and explain why it is important (don’t just define it), 50 words each: using heterozygosity to map migration, genetic drift, mimicry, Creation science and linkage disequilibrium

3) Should the origin of life be taught in Evolution? (I did not cover this concept, how life arose- abiogenesis, but many instructors cover this. – Look up the Miller-Urey experiment. Why would this be applicable to teaching the origin of life? 100 words

Human Immunodeficiency Virus

/in /by

The project is based on HIV…

Infectious diseases project

This project is a written academic paper or a PowerPoint (you pick):

1– Guidelines for the Academic Paper:

– Cover page: Include name of the disease and student(s) name

– Minimum of six paragraphs of the topic in an academic way. This work should have all of the following aspects about your disease: (Write each topic in the order given)

-Mention the organism(s) that cause the disease.

-Pick the most common organism that causes the disease and tell: Classification, organism’s habitat, general characteristics and virulence factors.

-Write how is the disease transmitted, what is the portal(s) of entry and, where does it cause problems in humans’ body.

-Signs and symptoms.

-Diagnosis and Treatment.

-Epidemiology: Include cases in U.S. and/or where is mostly present, who gets affected (kids, women, men, all), and it there are cases of nosocomial infections or not and why.

-Prevention.

— References

The style for the paper you decide it, just do it academically acceptable and interesting.

Environmental Politics and the Environment

/in /by

Please go the the League of Conservation Voters Scorecard website:

http://scorecard.lcv.org/ (Links to an external site.)

and research your state (of your primary residence) for each U.S. House of Representatives and U.S. Senate member. Determine how they have voted on environmental issues in 2019 and since they were originally elected to office?

2. Also go to this link http://scorecard.lcv.org/scorecard?year=2019 to determine how some of your state representatives voted on ‘Climate Change’ bills. (Links to an external site.)

3. Please make one original post to discuss your thoughts about how republicans and democrats vote based on environmental policy. Will this affect the way you vote in the future? Does this change by state……

4. Make sure to make 2 additional posts to other students original posts

Role of Biomarkers in Oncology

/in /by

Using the insights gained from your reading of chapter 21 of The Molecular Basis of Cancer textbook by Mendelsohn et al, write a convincing narrative on “The Role of Biomarkers in Oncology”. You must be original and display proper understanding of the core concepts and finding in the paper.

Writing Clues:

Use appropriate sub-headings to organize your essay and make it easy to read

Use specific and clear examples to highlight your understanding of the concepts

Use the appropriate scientific language and terminology for the topic and your scientific audience/readers/policy makers

Emphasize the clinical aspects of the topic – talk about specific diseases that relate to the topic.
