Procedure Time to Trace Part 1 ou are a molecule of oxygen floating happily through the atmosphere when all of a sudden you are inhaled by Ms. Magenta Trace your pathway through Me Magenta's respiratory tract begining in her nasal cavity to the point where you enter the pulmonary capillaries. rores naso Nasul eovts,extanul-nares, interna, Start: End 2 Trace your pathway from Ms. Magenta's pulmonary capillaries through her lungs and heart and to your final destination in a hepatocyte (liver cell). You likely will have to review Unit 17 (p. 411) for some help with this. Start: Palmonay aapillanes venals ulmanong vems in each lung lett atrium ef hort m hal yalue-rk ventric'e aorta-7abdevanal aona hepatueytcs End 3 Explain what happens to you in Ms. Magenta's hepatocyte. What do you do, and what do you become? (You can be somewhat general here in your answer unless your lab instructor says otherwise. You may have to refer to your textbook, and read about the basics of oxidative catabolism and the electron transfer system.) I Exploring Anatomy&Physiology; in the Laboratory

Explanation / Answer

3. ANS: After up taking oxygen molecules through the process of respiration the oxygen molecules can enters into the pulmonary capillaries and there the oxygen molecules can enters into the capillaries carried by hemoglobin in the blood to heart. The oxygen rich blood enters in to left atrium which then empties in to left ventricle. The aorta carries blood from left ventricle to all parts of the body. Oxygen is necessary to convert energy stirred in the nutrients to usable form ATP.

Ms. Magenta's hepatocytes role:

Hepatocytes are the major cells in the liver involved in metabolism, detoxification, and defense mechanism. Oxygen rich blood enters the liver through hepatic artery. Oxygen from blood enters the hepatocytes by diffusion. Hepatocytes have high level of enzymes for carbohydrate and amino acid metabolism. Once inside the cell the oxygen utilized in cellular respiration. Cellular respiration is a series of metabolic reactions which aim to produce energy from nutrients in the form if ATP. In this process glucose in the food is oxidized to produce carbon dioxide, ATP, and water.

Cellular respiration is composed of 4 stages:

1. Glycolysis: Glucose converted to pyruvate in cytosol.

2. Link reaction: Pyruvate converted to acetyl coA.

3. Krebs cycle: Takes place in mitochondrial matrix. Acetyl CoA is recycled to release necessary NADH and FADH2.

4. Electron transport chain: Membrane of mitochondria.

A. Electrons are passed from NADH to oxygen

B. Photons moved from matrix to inter membrane space

C. FADH2 donates electrons

D. Photons moving into the matrix by ATP synthase.

Hence ATP is produced.

In hepatocytes, through oxidative phosphorylation and electron transport chain in mitochondria Energy obtained from glycolysis is converted to ATP and released as energy.

At the final step the water molecules are formed during electron transferring end process.
