We have discussed the aerobic metabolism of glucose extensively in this class. To capture and use the energy in glucose to make ATP, we must utilize 4 different sequential pathways/steps. Starting with one glucose molecule and eventually ending with CO, H;O and ATP, list the 4 pathways/steps in order and tell me what molecules enter each pathway, and what the final products of each pathway are.

Understanding the Mechanism of Hemolytic Anemia Genetic defects in glycolytic enzymes can have serious consequences for humans For example, defects in the gene for pyruvate kinase can result in a condition known as hemolytic anemia. Consult a reference to learn about hemolytic anemia, and discuss why such genetic defects lead to this condition.
Indicate what will happen (increase, decrease or no effect) to the activity of enzyme or rate of the metabolic pathway given the following conditions: 1. release of glucagon in the blood to the activity of carnitine acyl transferase 1 2. phosphorylation of acetyl CoA carboxylase 3. low [carbon dioxide]/[oxygen gas] ratio to the oxygenase activity of RuBisCO
A rare, fake disease that I just made up called Leaky Inner Membrane Syndrome can lead to the formation of Hydrogen Ion Channel proteins within the inner membrane of the mitochondria. These channel proteins allow for the diffusion of hydrogen ions across the inner mitochondrial membrane according to their concentration gradient. Considering your knowledge of the electron transport chain and its role in oxidative phosphorylation, how would this disease affect the metabolism of an affected individual? Be specific!
After pyruvate is formed, it must either be converted to another molecule to enter the citric acid cycle and ultimately produce ATP by utilizing the electron-transport chain, or go through alternate pathways to produce NAD Identify the products formed in the pathway of pyruvate and indicate whether NADH+H or NAD are produced under aerobic and anaerobic respiration Drag the appropriate labels to their respective targets. ▸ View Available Hint(s) Reset Help Alcohol (ethanol) Aerobic Respiration Anaerobic Respiration Acetyl coenzyme A Normal cell Yeast Lactate NAD+ produced NADH+H* produced Submit End products NAD*/ NADH+H* Previous Answers Request Answer Group 1 Group 2 Exercising Muscle Lactate Group 2 Group 1 Group 2
Describe the process of oxidative phosphorylation. In your description, include the terms NADH, FADH2, ATP, mitochondria (or mitochondrial), glycolysis, citric acid cycle, electron (or electrons), proton (or protons), and oxygen. Be sure to describe how ATP molecules get produced, and how many ATP molecules are produced per FADH2 and NADH (note; NADH from outside the mitochondria generate a different number of ATP compared to NADH inside the mitochondria; your description should indicate both quantities for full credit.) vas 19llo ton lle vowor 1esb
