Your question: What are the 3 metabolic pathways of cellular respiration?

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain.

What are the three metabolic processes of cellular respiration?

The overall process, however, can be distilled into three main metabolic stages or steps: glycolysis, the tricarboxylic acid cycle (TCA cycle), and oxidative phosphorylation (respiratory-chain phosphorylation).

What are the three main metabolic pathways involved in cellular respiration quizlet?

The cellular respiration process consists of three stages: glycolysis, the Krebs cycle, and the electron transport chain. glycolysis, the six-carbon sugar molecule (glucose) breaks down into 2 three-carbon molecules (pyruvic acid). The energy of the broken bonds is captured, yielding two molecules of ATP.

What are two pathways of cellular respiration?

You have just read about two pathways in cellular respiration—glycolysis and the citric acid cycle—that generate ATP.

What are the 3 phases of cellular respiration where does each phase occur?

The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3). Figure below gives an overview of these three stages, which are further discussed in the concepts that follow.

What are the steps in cellular respiration?

The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

What is the cellular respiration formula?

Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O.

What are the three main metabolic pathways?

There are three metabolic pathways that provide our muscles with energy: the phosphagen pathway, the glycolytic pathway, and the oxidative pathway.

What hormone is most responsible for determining the basal metabolic rate?

The basal metabolic rate is mostly determined by the thyroid hormones T3 and T4, which respond to thyroid-stimulating hormone (TSH). 3 T3 and T4 bind to mitochondria receptors, increasing adenosine triphosphate (ATP) production and increasing glucose use. ATP helps with the transportation and use of energy.

What are the 2 metabolic pathways a cell can use and what does it depend on which pathway is used?

What are the 2 metabolic pathways a cell can use and what determines which pathway is used? They are aerobic and anaerobic and are determined by oxygen. … What are the 3 phases of the aerobic cellular respiration process? They are Glycolysis, the Kreb’s cycle, and the Electron Transport.

Is Calvin cycle part of cellular respiration?

The Calvin cycle is part of the light-independent reactions of photosynthesis. The Calvin cycle uses ATP and NADPH. The Krebs cycle is part of cellular respiration. This cycle makes ATP and NAPH.

What is the process of cellular respiration called when oxygen is not present?

When oxygen is not present and cellular respiration cannot take place, a special anaerobic respiration called fermentation occurs. Fermentation starts with glycolysis to capture some of the energy stored in glucose into ATP.

What does succinate do in cellular respiration?

Succinate plays a pivotal role in oxidative metabolism. Succinate is a tricarboxylic acid (TCA) cycle intermediate that interacts directly with the mitochondrial electron transport chain (ETC), enabling a ‘shortcut’ route to ATP production via oxidative metabolism.

What are the 3 main parts of cellular respiration?

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain.

What are the two phases of aerobic respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain.

What is the correct order for the three steps of aerobic respiration?

Aerobic respiration has three stages: glycolysis, Krebs cycle, and the electron transport chain.
