What reactants does Krebs cycle have?
Fuel for the Krebs cycle comes from lipids (fats) and carbohydrates, which both produce the molecule acetyl coenzyme-A (acetyl-CoA). This acetyl-CoA reacts in the first step of the eight step sequence of reactions that comprise the Krebs cycle, all of which occur inside mitochondria of eukaryotic cells.
What are the two products of the Krebs?
Two products of the Krebs cycle are NADH and FADH2.
What are the products of the Krebs preparation?
Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.
What are the inputs and outputs of Krebs cycle?
A good estimate is about 2-3 ATP per NADH and 1.5 ATP per FADH2. A very efficient cell can produce a total of 38 ATP from a single glucose molecule….The Electron Transport Chain: Mass-Producing ATP.
| Process | Citric Acid Cycle (Krebs Cycle) |
|---|---|
| Location | Mitochondria (Matrix) |
| Input | 2 Acetyl-CoA |
| Output | 2 ATP 6 NADH 2 FADH2 4 CO2 |
What are the reactants in the citric acid cycle?
Products
| Description | Reactants | Products |
|---|---|---|
| The sum of all reactions in the citric acid cycle is: | Acetyl-CoA + 3 NAD+ + FAD + GDP + Pi + 2 H2O | → CoA-SH + 3 NADH + FADH2 + 3 H+ + GTP + 2 CO2 |
What are the net inputs and outputs of oxidative phosphorylation?
Oxidative phosphorylation is the process by which ATP is synthesised when electrons are transported from the energy precursors produced in the citric acid cycle through various enzyme complexes to molecular oxygen. The input is NADH, FADH2, O2 and ADP. The output is NAD+, FAD+, H2O and ATP.
What are the major end products of oxidative phosphorylation?
The end product of oxidative phosphorylation is ATP and water.
What are the net products of oxidative phosphorylation?
Two net ATP are made in glycolysis, and another two ATP (or energetically equivalent GTP) are made in the citric acid cycle….ATP yield.
| Stage | Direct products (net) | Ultimate ATP yield (net) |
|---|---|---|
| Citric acid cycle | 2 ATP/GTP | 2 ATP |
| 6 NADH | 15 ATP | |
| 2 FADH 2 | 3 ATP | |
| Total | 30-32 ATP |
Is NADH a reactant or product?
The main biochemical reactants of the ETC are the electron donors succinate and nicotinamide adenine dinucleotide hydrate (NADH). These are generated by a process called the citric acid cycle (CAC). Fats and sugars are broken down into simpler molecules such as pyruvate, which then feed into the CAC.
What are the products of oxidative phosphorylation used for?
The energy stored in the chemical bonds of glucose is released by the cell in the citric acid cycle producing carbon dioxide, and the energetic electron donors NADH and FADH. Oxidative phosphorylation uses these molecules and O2 to produce ATP, which is used throughout the cell whenever energy is needed.
