Cell Respiration Warm Up 1

The correct answer is Glycolysis Cycle, Krebs Cycle, Electron Transport Chain. Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. The first phase, glycolysis, occurs in the cytoplasm and breaks down glucose into two molecules of pyruvate. The second phase, the Krebs cycle, takes place in the mitochondria and further breaks down pyruvate to produce energy-rich molecules. The final phase, the electron transport chain, also occurs in the mitochondria and uses the energy from the previous phases to generate ATP, the cell's main energy source.

Glycolysis, which is the first step of cellular respiration, occurs in the cytoplasm of the cell. It is a metabolic pathway that breaks down glucose into pyruvate, producing a small amount of ATP and NADH in the process. Since the cytoplasm is the fluid-filled region between the cell membrane and the nucleus, it is the correct location for glycolysis to take place.

The Krebs Cycle, also known as the citric acid cycle, is the phase of cellular respiration where carbon dioxide is produced. This cycle takes place in the mitochondria and is a series of chemical reactions that convert pyruvate, a product of glycolysis, into carbon dioxide. During the Krebs Cycle, carbon dioxide is released as a waste product, along with the production of ATP and electron carriers. Therefore, the correct answer is Krebs Cycle.

The Krebs (Citric Acid) Cycle, also known as the citric acid cycle or the tricarboxylic acid cycle, occurs in the mitochondrial matrix. The mitochondrial matrix is the innermost compartment of the mitochondria, surrounded by the inner mitochondrial membrane. This is where the cycle takes place and involves a series of chemical reactions that ultimately generate energy in the form of ATP. The other options, such as the outer membrane, cristae, nuclear membrane, and Golgi Apparatus, are not involved in the Krebs Cycle.

In the Kreb's Cycle part of cellular respiration, 2 ATP (adenosine Triphosphate) molecules are made. This cycle occurs in the mitochondria and is responsible for generating energy in the form of ATP through a series of chemical reactions. The Kreb's Cycle produces a small amount of ATP directly, while the majority of ATP is produced through the electron transport chain, which follows the Kreb's Cycle.

The correct answer is Electron Transport Chain. During the electron transport chain phase of cellular respiration, water is made as a byproduct. This process occurs in the inner mitochondrial membrane, where electrons are passed along a series of protein complexes, generating energy and creating a proton gradient. At the end of the chain, the electrons combine with oxygen and hydrogen ions to form water.

In the glycolysis cycle of cellular respiration, a net of 2 ATP molecules are produced. Glycolysis is the initial step of cellular respiration and occurs in the cytoplasm. During glycolysis, glucose is broken down into two molecules of pyruvate, and in the process, 4 ATP molecules are produced. However, 2 ATP molecules are also consumed in the initial steps of glycolysis, resulting in a net production of 2 ATP molecules. Therefore, the correct answer is 2.

The correct answer is 34. During the Electron Transport Chain (ETC) part of cellular respiration, ATP is produced through oxidative phosphorylation. Each NADH molecule that enters the ETC can produce approximately 3 ATP, while each FADH2 molecule can produce approximately 2 ATP. Since 10 NADH and 2 FADH2 molecules are produced during the previous steps of cellular respiration, the total ATP production from the ETC is 10(3) + 2(2) = 34 ATP.

In the Electron Transport and chemiosmosis part of cellular respiration, a total of 34 ATP molecules are produced. This process occurs in the inner mitochondrial membrane, where electrons from NADH and FADH2 are transferred along a series of protein complexes. As these electrons move through the complexes, hydrogen ions are pumped across the membrane, creating a gradient. The potential energy from this gradient is then used by ATP synthase to produce ATP. Overall, this process generates a net of 34 ATP molecules, making it the correct answer.

The electron transport chain, which is a crucial step in cellular respiration, occurs in the mitochondrial cristae. The cristae are the folded inner membranes of the mitochondria, providing a large surface area for the electron transport chain to take place. This is where the final stage of cellular respiration occurs, where electrons are transferred along a series of protein complexes, generating ATP and water.
