Where Does The Second Stage Of Cellular Respiration Occur?

The second stage of cellular respiration, called the Krebs cycle , takes place

in the matrix of a mitochondrion

.

Where does the second major part of cellular respiration take place?

The citric acid cycle (also known as the Krebs cycle) is the second pathway in cellular respiration, and it also takes place in

the mitochondria

.

What happens in the 2nd stage of cellular respiration?

The second step in cellular respiration is called

the Krebs cycle

. The Krebs cycle uses pyruvic acid to create ATP, along with additional molecules like NADH, FADH2, and CO2. The NADH and FADH2 molecules are used during the final step of cellular respiration, while the CO2 is exhaled.

What happens in the second stage of cellular respiration and where does it occur in the cell?

Stage 2:

The Krebs Cycle

That’s where the second stage of cellular respiration takes place. This stage is called the Krebs cycle. During this stage, two more molecules of ATP are produced. Other energy-storing molecules are also produced (to be used to make more ATP in stage 3).

Where do the 3 stages of respiration occur?

The three main stages of cellular respiration (aerobic) would include

Glycolysis in the cytoplasm

, the Kreb’s Cycle in the Mitochondrial Matrix and the Electron Transport Chain in the Mitochondrial Membrane.

Where does each stage of cellular respiration occur?

The cellular respiration process includes four basic stages or steps:

Glycolysis

, which occurs in all organisms, prokaryotic and eukaryotic; the bridge reaction, which stets the stage for aerobic respiration; and the Krebs cycle and the electron transport chain, oxygen-dependent pathways that occur in sequence in the …

What are the three parts of cellular respiration?

Cellular respiration is made up of three sub-processes:

glycolysis, the Citric Acid Cycle (Krebs Cycle), and the Electron Transport Chain (ETC)

.

How does the second stage of cellular respiration benefit a cell?

How does Stage 2 of cellular respiration benefit a cell? Stage 2:

Small molecules are broken down further using oxygen and releasing much more energy

. Breathing brings in oxygen that is used in cellular respiration and removes waste products such as carbon dioxide.

Is energy released in the second stage of cellular respiration?

These two molecules go on to stage II of cellular respiration. The energy needed to split glucose is provided by two molecules of ATP. As

glycolysis

proceeds, energy is released, and the energy is used to make four molecules of ATP.

Who discovered the second stage of cellular respiration?

The second stage of cellular respiration is the transfer of the energy in pyruvate, which is the energy initially in glucose, into two energy carriers, NADH and FADH

₂

. A small amount of ATP is also made during this process. This process occurs in a continuous cycle, named after its discover,

Hans Krebs

.

What is the stages of cellular respiration?

The stages of cellular respiration include

glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation

.

In which two parts of a mitochondrion does cellular respiration take place?

Mitochondria, organelles specialized to carry out aerobic respiration, contain an inner membrane folded into cristae, which form two separate compartments:

the inner membrane space and the matrix

. The Krebs Cycle takes place in the matrix.

What is the relationship between photosynthesis and cellular respiration?

Photosynthesis converts carbon dioxide and water into oxygen and glucose

. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What are the two stages of respiration?

Stages of Cellular Respiration

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).

What is the main goal of cellular respiration?

In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. The goal of cellular respiration is

to capture this energy in the form of ATP

.

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.
