Where does the citric acid cycle occur?
Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Which letter indicates the process during which oxygen is consumed quizlet?
Which letter (s) indicate the process during which oxygen is consumed? Oxidative phosphorylation is the process by which ATP is formed as a result of the transfer of electrons from NADH or FADH2 to O2 (molecular oxygen) by a series of electron carriers.
What process occurs in structure H photosynthesis?
Terms in this set (13) What process occurs in structure H? Photosynthesis produces glucose and releases oxygen into the atmosphere.
Where does oxidative phosphorylation take place in human cells?
mitochondria Oxidative phosphorylation is the process where energy is harnessed through a series of protein complexes embedded in the inner-membrane of mitochondria (called the electron transport chain and ATP synthase) to create ATP.
Where does the citric acid cycle occur quizlet?
The Citric acid cycle occurs in the mitochondria. The most important structural feature of mitochondria are the inner membrane, the matrix (where the enzymes are dissolved), and the cristae (the infoldings of the inner membrane).
Why does citric acid cycle occur in mitochondria?
The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step. Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP.
Where in the cell does respiration where oxygen is consumed and carbon dioxide is excreted take place?
Gas Exchange Between Alveolar Spaces and Capillaries The function of the respiratory system is to move two gases: oxygen and carbon dioxide. Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them.
How is oxygen consumed during cellular respiration?
Answer and Explanation: The oxygen consumed during cellular respiration is involved directly in accepting electrons at the end of the electron transport chain.
What process occurs in Box B?
What process occurs within Box B? The citric acid cycle transfers electrons to NADH and FADH2. What molecule is indicated by the letter D? Oxygen is the final electron acceptor of cellular respiration.
How do the roles of ubiquinone and cytochrome c differ from the other components of the electron transport chain?
Moreover, Q is the only component of the electron transport chain that is not a protein. Ubiquinone and cytochrome c are small, mobile electron carriers, whereas the other components of the electron transport chain are large complexes anchored in the inner mitochondrial membrane.
What does cytochrome c do in the electron transport chain?
Cytochrome c is functionally involved in the electron transport chain of mitochondria. That electron transport is part of the pathway for synthesis of ATP. The role of cytochrome c is to carry electrons from one complex of integral membrane proteins of the inner mitochondrial membrane to another (Fig. 10.3).
Which process occurs within the mitochondria?
The process is called oxidative phosphorylation and it happens inside mitochondria. In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).
Where does the citric acid cycle occur in the mitochondria quizlet?
The Citric Acid Cycle occurs in the inner mitochondrial matrix.
Where does the citric acid cycle occur in eukaryotes quizlet?
Where do the reactions of the citric acid cycle occur in eukaryotic cells? Correct. The citric acid cycle, which takes place in the mitochondrial matrix, completes the degradation of glucose.
Does the citric acid cycle occur in the cytoplasm?
Overview of the citric acid cycle In eukaryotes, the citric acid cycle takes place in the matrix of the mitochondria, just like the conversion of pyruvate to acetyl CoAstart text, C, o, A, end text. In prokaryotes, these steps both take place in the cytoplasm.
Where does the carbon dioxide come from in cellular respiration?
Carbon dioxide is transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled. ATP is generated in the process. When one molecule of glucose is broken down, it can be converted to a net total of 36 or 38 molecules of ATP. This only occurs in the presence of oxygen.
Where within the cell does the process of respiration take place?
mitochondria While most aerobic respiration (with oxygen) takes place in the cell's mitochondria, and anaerobic respiration (without oxygen) takes place within the cell's cytoplasm.
How are photosynthesis and cellular respiration related Brainly?
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.
What process occurs in Box B mastering biology?
What process occurs within Box B? The citric acid cycle transfers electrons to NADH and FADH2. What molecule is indicated by the letter D? Oxygen is the final electron acceptor of cellular respiration.
What is the function of structure e?
What is the function of Structure E? stabilization of the phospholipids; Cholesterol helps to stabilize the structure of the plasma membrane.
How does cytochrome c differ to other proteins that participate in the electron transport chain?
Cytochrome c is highly water-soluble, unlike other cytochromes, and is an essential component of the respiratory electron transport chain, where it carries one electron. It is capable of undergoing oxidation and reduction as its iron atom converts between the ferrous and ferric forms, but does not bind oxygen.
Where is cytochrome c located what is its function?
Cytochrome c is a heme protein that is localized in the compartment between the inner and outer mitochondrial membranes where it functions to transfer electrons between complex III and complex IV of the respiratory chain.
Where is cytochrome c in mitochondria?
mitochondrial intermembrane/intercristae spaces Abstract. In healthy cells, cytochrome c (Cyt c) is located in the mitochondrial intermembrane/intercristae spaces, where it functions as an electron shuttle in the respiratory chain and interacts with cardiolipin (CL).
What process occurs in the cytoplasm?
Cytoplasm Functions Many cellular processes also occur in the cytoplasm, such as protein synthesis, the first stage of cellular respiration (known as glycolysis), mitosis, and meiosis. The cytoplasm helps to move materials, such as hormones, around the cell and also dissolves cellular waste.
What process occurs in the mitochondria quizlet?
What cell process occurs in the mitochondria? Aerobic cellular respiration.
Why does the citric acid cycle take place in the mitochondria?
The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step. Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP.
Where does the citric acid cycle occur in prokaryotes?
In prokaryotic cells, the citric acid cycle occurs in the cytoplasm; in eukaryotic cells the citric acid cycle takes place in the matrix of the mitochondria.
Does the citric acid cycle occur in chloroplast?
Where does the citric acid (Krebs) cycle occur in human cells? Explanation: The citric acid (Krebs) cycle takes place in the mitochondrial matrix. The Krebs cycle involves using acetyl-CoA as a substrate to produce high energy electron carriers and to later participate in electron transport, ultimately yielding .
Where does carbon dioxide come from in the body?
Cellular respiration converts ingested nutrients in the form of glucose (C6H12O6) and oxygen to energy in the form of adenosine triphosphate (ATP). CO2 is produced as a byproduct of this reaction. The O2 needed for cellular respiration is obtained via inhalation.
Which process occurs in the cytoplasm?
Cytoplasm Functions Many cellular processes also occur in the cytoplasm, such as protein synthesis, the first stage of cellular respiration (known as glycolysis), mitosis, and meiosis. The cytoplasm helps to move materials, such as hormones, around the cell and also dissolves cellular waste.
