This week you will apply everything you’ve learned about digestion, absorption, metabolism, transport, and biochemical regulation by exploring one of the clinical cases from Section 4. Your goal is to investigate the real-world biochemistry behind the condition: what the data show, how common it is, what biomarkers change, and why the underlying molecular pathways matter for nutrition and nursing practice.

This activity helps you connect biochemical concepts to the lived experience of patients and to current research in healthcare.

Step 1: Choose ONE case from Section 4

You may pick any of the following:

• Type 2 Diabetes & Metabolic Syndrome
• Iron-Deficiency Anemia in Pregnancy
• Cardiovascular Risk & Dyslipidemia
• Post-Surgical Recovery & Protein Needs
• (Optional) Alcohol-Related Thiamine Deficiency

---

Step 2: Create Your Main Post

Title:
Case Study: [Name of the Case You Chose]

Your post must include all of the following:

1. List at least 3 reliable sources

Choose peer-reviewed articles, clinical guidelines, government health sites, or scientific news outlets.
Examples: CDC, NIH, WHO, Mayo Clinic, PubMed articles, academic journals.

---

2. Present at least 3 sets of data or statistics related to your case

These may include (examples):

• Prevalence or incidence rates
• Lab values or diagnostic cutoffs (e.g., HbA1c ranges for diabetes)
• Risk factors or demographic trends
• Biochemical measurements (lipid levels, iron status indicators, ketone levels)
• Effects of an intervention (dietary change, medication, supplementation)

Be sure to explain the significance of each data point.

3. A 200-word reflection connecting your case to biochemistry

In your reflection, discuss:

• The biochemical pathways involved (digestion, metabolism, transport, enzymes, hormones)
• How these pathways explain symptoms, risk factors, or lab results
• How nutrition and nursing recommendations align with biochemical mechanisms
• Why understanding the molecular details matters for patient care

Aim for clarity, depth, and thoughtful connections.

---

Step 3: Respond to at least TWO classmates

Your replies must include:

• A minimum 100-word reflection on their topic
• One thoughtful question for the author about their case
• • This could relate to biochemical mechanisms, data interpretation, or clinical implications

Examples:

• How might insulin resistance alter this pathway?
• Would a change in nutrient absorption impact your patients outcomes?
• What additional biomarkers would you monitor?

Make your responses encouraging, analytical, and curiosity-driven.

What This Activity Reinforces

By completing this discussion, you will practice:

• Reading and interpreting scientific evidence
• Connecting biochemical pathways to real health conditions
• Communicating science clearly and professionally
• Applying course concepts to nutrition and nursing practice

Instructions for Creating the Scientific Poster

You are required to design a clear, well-organized scientific poster on the topic Crystal Structure of Human Monoamine Oxidase A with Harmine. The poster should effectively communicate key concepts in a simple and visually appealing way, suitable for students with a foundational understanding of biochemistry.

Start with a clear and prominent title at the top of the poster. Below the title, organize the content into three main sections: Background, Structure, and Mechanism of Action. Each section should be concise and presented using bullet points or short phrases instead of long paragraphs.

In the Background section, briefly explain what monoamine oxidase A (MAOA) is and its biological role. Mention that it is a mitochondrial outer membrane enzyme involved in the breakdown of neurotransmitters and that it is an important target in mental health research. Introduce harmine as an inhibitor and its relevance to studying MAOA.

In the Structure section, describe the key structural features of MAOA, including its membrane-bound nature and the presence of a transmembrane helix. Highlight important amino acid differences (e.g., Ile-335 vs. Tyr-326 in MAOB) that influence inhibitor selectivity. Keep explanations straightforward and avoid overly technical detail.

In the Mechanism of Action section, explain how harmine interacts with MAOA and how structural elements like loop 108118 contribute to enzyme function. Include the role of specific residues such as G110 and how membrane anchoring affects enzyme flexibility and activity.

Add at least one simple, labeled diagram to illustrate either the enzyme structure or inhibitor binding. Ensure the layout is clean, with consistent fonts, clear headings, and balanced spacing. Use color sparingly to improve readability.

Keep the poster limited to one page and focus on clarity over complexity.

Instructions for Creating the Poster

You are required to design a clear and visually engaging scientific poster based on the topic Crystal Structure of Human Monoamine Oxidase A with Harmine. The poster should be simple, informative, and suitable for an academic audience with a basic understanding of biochemistry.

Begin with a concise and bold title at the top of the poster. Directly below, include clearly labeled sections: Background, Structure, and Mechanism of Action. Each section should contain brief, easy-to-read bullet points rather than long paragraphs.

In the Background section, explain that monoamine oxidase (MAO) is a mitochondrial outer membrane enzyme responsible for breaking down amines. Mention that MAOA and MAOB are important in mental health research and drug development. Keep this explanation simple and focused on relevance.

In the Structure section, highlight the key structural differences between MAOA and MAOB, specifically referencing residues such as Ile-335 and Tyr-326. Note the presence of the C-terminal transmembrane helix and its importance. Use simplified language to explain how structural differences influence inhibitor selectivity.

In the Mechanism of Action section, describe the role of loop 108118 and the significance of the G110 mutation. Emphasize how membrane anchoring affects enzyme activity and flexibility. Avoid excessive technical jargonfocus on clarity.

Include at least one simple diagram or labeled illustration (e.g., enzyme structure or membrane interaction) to support understanding. Use consistent fonts, clear headings, and a logical layout. Apply color sparingly to differentiate sections and improve readability.

Ensure the poster is neat, visually balanced, and does not exceed one page. The goal is to communicate key ideas effectively, not to overload with detail.

Human Organ Systems

Organs in the human body function as part of an integrated group of structures known as organ systems. Examples of organ systems are as follows:

• Cardiovascular system
• Digestive system
• Musculoskeletal system
• Nervous system
• Excretory system
• Endocrine system
• Respiratory system

These organ systems are responsible for crucial processes necessary for sustaining life, often working together, interacting with other organs in a functional network that keeps the body in balance (homeostasis). When homeostasis (the normal functioning of organ systems) is disrupted, disease may develop, causing injury to the body or even death.

1. Choose 1 case study to explore a disease or organ malfunction:
2. Click on the case study of your choice above to view the questions for that topic. Present your answers to the questions in the form of a 23-page paper.
3. Utilize at least 2 credible sources to support the arguments presented in the paper. Make sure that you cite them appropriately within your paper, and list the references in APA format on your Reference page.
4. Refer to your assigned textbook Concepts in Biology, Chapter 16.3: Circulatory and Respiratory Systems for help.
5. Formatting guidelines: In accordance with APA formatting requirements, your paper should include Title and Reference pages; should be double-spaced; and should include a running head and page numbers. Your paper should be 23 pages in length, not counting the Title page, and Reference page.

How does disruption of metabolic pathways contribute to diseases such as , and can these pathways be effectively targeted for treatment?
