Question

In the citric acid cycle (also known as the Krebs cycle), acetyl CoA is completely oxidized. From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of the citric acid cycle. Drag each compound to the appropriate bin. If a compound is not involved in the citric acid cycle, drag it to the "not input or output" bin. (Note that not all of the inputs and outputs of the citric acid cycle are included.)

Answer 1

Answer:

We place ( O₂, CO₂, coenzyme A and acetyl CoA) into bin [not input or output];

We place (ADP, NAD⁺, Glucose) into [ Net Input] bin.;

And (ATP, NADH and Pyruvate) intothe [Net Output] bin.

Explanation:

Citric Acid Cycle is also known as Tricarboxylic Acid Cycle, Krebs Cycle and Szent-Györgyi-Krebs cycle.

It is a series of enzyme-catalyzed chemical reactions, which of central importance in all living cells that use oxygen as part of cellular respiration.

Here are few things to know about the CAC:

• The Krebs cycle uses the products of Glycolysis to produce 2 ATP molecules for each molecule of Glucose.

• Oxygen is required.

• The Krebs Cycle occurs in cellular power plant — Mitochondria of the cell.

• Each glucose molecule nets 2 pyruvic acids. The Krebs Cycle breaksdown 1 pyruvic acid one at å time.

• CAC begins and ends with Oxaloacetic Acid - a 4 carbon molecule.

• It is an 8 step cycle that begins when the Acetyl CoA that is a product of Glycolysis is 'picked up' by Oxalacetic Acid.

• Lipids, Proteins and Carbohydrates can all be metabolized in the Krebs Cycle.

• The NADH and FADH2 that are high energy co- enzymes (helper molecules) are by-products of the Krebs cycle and continue on to fuel the Electron Transport Chain.

The clues above helps us to know where to drag the compounds into;

We place these into bin of [Net Input]: ADP, NAD⁺, Glucose

We place these into the bin of [Net Output]: ATP, NADH and Pyruvate,

We place the following into [not input or output] bin: O₂, CO₂, coenzyme A and acetyl CoA
