Energy Storage Summary Most energy is stored as triglycerides in our adipocytes (> 15 kg, equivalent to more than 100 000 kcal !!!! Carbohydrate stored as: glycogen in liver (~150 g); most concentrated as liver is only ~2 kg! glycogen in muscle (~350 g); ~40% body mass is muscle only about 30 g of glucose is found in the blood – not much!** Protein also represents a large potential energy source (since we' re about 40% muscle). This represents about 25 000 kcal, but is obviously protected i.e. used in starvation or caloric restriction ** Consider a large meal at ~1000 kcal, and 60% carbohydrate – that's 150 grams of CHO! Yet your blood only holds 30 g!
Which statement is not completely true? O Stage 3 is composed of the citric acid cycle, and the elecrtron transport chain coupled with oxidative phosphorylation. O Anabolism are reactions involved in the breakdown of biomolecules energy is released. O The ultimate goal of the 3 stages of catabolism is to regenerate ATP from ADP. O In Stage 2 of Catabolism, the main energy molecule that all macronutrients are broken down into is Acetyl groups (combined with the shuttle CoA) to form Acetyl COA. O An array of chemical reactions (series of steps) that are organized into orderly well regulated sequences are called metabolic pathways. O The purpose of the citric acid cycle is to regenerate NAD* and FAD to NADH and FADH2

SC5 x .core.learn.edgenuity.com/player/ cience - SC5181 A ✓ 21 23 24 25 How does cellular respiration demonstrate an energy transformation? O The carbon from glucose is assimilated into high-energy bonds of carbon dioxide that get released into the air. O Chemical energy gets used up during the breakdown of glucose into carbon dioxide and water. O Chemical energy is released when glucose molecules are hydrolyzed into waste products. O The energy produced from the breakdown of carbon dioxide gets taken up by the formation of glucose molecules.

Heading 1 Editing ont Paragraph Styles 10. Triglycerides are major energy storage molecules. Which statement about the complete oxidation of triglycerides to CO2 and water and the oxidation of glucose to CO, and water is true? C They are both endergonic. Glucose oxidation and triglyceride oxidation use glycolysis. Both generate the same ratio of moles of ATP per mole of fuel molecule oxidized. ATP is hydrolyzed at some point in both pathways. Both the complete oxidation of triglycerides and that of glucose use acetyl CoA as an intermediate. 11.

1. Energy Metabolism Pathways The body uses carbohydrates, fats, and proteins to fuel all its activities. These fuels each start down a different path, but they all ultimately end up providing energy by going through the TCA cycle and electron transport chain. Identify which compounds can be formed during metabolism from each fuel source. Fuel Sources Glucogenic amino acids Ketogenic amino acids Glycerol Glucose Fatty acids Compounds Formed During Metabolism Acetyl CoA ▬ ✓ 0 0 n Pyruvate Lactate Glucose Fat ✓ □ 0 0 n 0 n ☐ □ 0 0 0 C 00 0 0 0 0 Use your knowledge of metabolism to determine if the activity described is occurring in aerobic or anerobic conditions.
hiii please help me understand this activity. thanks
You are running. Glycogen is broken down into glucose-6-phosphate which goes through the glycolytic, citric acid cycle and electron transport pathways and is turned into ATP. This process is called: aerobic respiration beta-oxidation gluconeogenesis ketoacidosis
