Which metabolic pathways are not connected to cellular respiration? breakdown and synthesis of proteins All of these are connected breakdown and synthesis of lipids breakdown and synthesis of carbohydrates Energy is stored long-term in the bonds of _____ and used short-term to perform work from a(n) _____ molecule. an anabolic molecule: catabolic molecule glucose: ATP ATP: glucose a catabolic molecule: anabolic molecule

Solution

1. Option B (All are connected) is the correct answer.

How carbohydrates enter the pathway:Most carbohydrates enter cellular respiration during glycolysis. In some cases, entering the pathway simply involves breaking a glucose polymer down into individual glucose molecules.

How proteins enter the pathway: When you eat proteins in food, your body has to break them down into amino acids before they can be used by your cells. Most of the time, amino acids are recycled and used to make new proteins, not oxidized for fuel.

How fats enter the pathway: Fats, known more formally as triglycerides, can be broken down into two components that enter the cellular respiration pathways at different stages.
