What process occurs in Box A biology quizlet?
What process occurs in Box A? (A scheme of cellular respiration. At box A, which is located in the cytosol, glucose turns into pyruvate with release of ATP and electrons carried by NADH. Pyruvate from this stage is used in a cycle in box B, which is located in the mitochondrion.
What process occurs in structure H mastering biology quizlet?
Chloroplasts are the sites of photosynthesis. What process occurs in structure H? Photosynthesis produces glucose and releases oxygen into the atmosphere.
What starts the process of glucose oxidation?
Glycolysis produces 30 ATP from each molecule of glucose. It requires ATP and NADH. It converts one glucose molecule to two molecules of pyruvate and carbon dioxide. It represents the first stage in the chemical oxidation of glucose by a cell.
Where do the processes indicated by the letter C occur?
Where do the processes indicated by the letter C occur? Locations of key reaction pathways and ATP production within the cell.
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.
Where does glycolysis occur in a eukaryotic cell?
cytoplasm Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Where does the Calvin cycle take place in the cell?
stroma Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
Where does oxidation occur in glycolysis?
Glycolysis occurs in the cytoplasm where one 6 carbon molecule of glucose is oxidized to generate two 3 carbon molecules of pyruvate. The fate of pyruvate depends on the presence or absence of mitochondria and oxygen in the cells.
Does oxidation occur in glycolysis?
Catabolic pathway during which a 6 carbon glucose molecule is split into two 3 carbon sugars which are then oxidized and rearranged by a step-wise metabolic process that produces two molecules of pyruvic acid. No CO2 is released in the oxidation of glucose to pyruvate.
Where does glycolysis take place?
the cytoplasm Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Where does pyruvate oxidation occur?
mitochondrial matrix Pyruvate is produced by glycolysis in the cytoplasm, but pyruvate oxidation takes place in the mitochondrial matrix (in eukaryotes). So, before the chemical reactions can begin, pyruvate must enter the mitochondrion, crossing its inner membrane and arriving at the matrix.
What process occurs in Box B overview of cellular respiration?
What process occurs within Box B? The citric acid cycle transfers electrons to NADH and FADH2.
In which reactions of cellular respiration does substrate level phosphorylation occur?
Substrate-‐level phosphorylation occurs in glycolysis and in the citric acid cycle (a part of cellular respiration).
Where does glycolysis occur in the prokaryotic cell?
Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells.
Where does glycolysis occur in a eukaryotic cell quizlet?
In eukaryotic cells, glycolysis occurs in the cytosol. The breakdown of one glucose molecule by glycolysis yields a net gain of 16 ATP. The end products of glycolysis include water, carbon dioxide, and ATP. At the end of pyruvate oxidation, acetyl-CoA is phosphorylated into ATP.
Where does Calvin cycle occur in C4?
bundle sheath cell In C4 plants the photosynthesis takes place in a thin-walled mesophyll cell and a 4-carbon acid is handed off to a thick-walled bundle sheath cell, where the Calvin cycle occurs in a chloroplast of that second cell. This protects Calvin cycle from the effects of photorespiration.
Where does the Calvin cycle occur AB?
The Calvin Cycle occurs in the stroma of a chloroplast in a plant cell. The stroma is the colorless fluid that surrounds the grana of the chloroplast, where the first step of photosynthesis takes place.
Where does pyruvate processing occur?
the mitochondrial matrix The mitochondrion has a double membrane, and the space inside the inner membrane is called the matrix. So pyruvate processing and the citric acid cycle take place inside the mitochondrial matrix.
Where does reduction occur in glycolysis?
There is one redox reaction during glycolysis. The oxidation of glucose begins during glycolysis. NAD+ accepts the electrons during the oxidation, and as a result it gets reduced.
Where does oxidation takes place in glycolysis?
D. In glycolysis, oxidation takes place when 3- phosphoglyceraldehyde is converted to 1,3- bisphosphoglycerate, where NAD is reduced to NADH.
What occurs glycolysis?
Glycolysis occurs in the cytoplasm where one 6 carbon molecule of glucose is oxidized to generate two 3 carbon molecules of pyruvate. The fate of pyruvate depends on the presence or absence of mitochondria and oxygen in the cells.
Where does the beta-oxidation occur?
Oxidation of fatty acids occurs in multiple regions of the cell within the human body; the mitochondria, in which only Beta-oxidation occurs; the peroxisome, where alpha- and beta-oxidation occur; and omega-oxidation, which occurs in the endoplasmic reticulum.
Where in the cell does the glycolysis occur?
the cytoplasm Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Where does phosphorylation occur in cellular respiration?
Substrate-level phosphorylation occurs in the cytoplasm of cells (glycolysis) and in the mitochondria (Krebs cycle).
Where does oxidative phosphorylation occur?
Most of the usable energy obtained from the breakdown of carbohydrates or fats is derived by oxidative phosphorylation, which takes place within mitochondria.
Where does glycolysis occur in prokaryotes and eukaryotes?
Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells. Glucose enters heterotrophic cells in two ways.
Where does gluconeogenesis occur in the cell?
Gluconeogenesis starts in the mitochondria of the cells. In the first step, carboxylation of pyruvate occurs by pyruvate carboxylase enzyme and it forms oxaloacetate by using one ATP molecule. Oxaloacetate is reduced to malate by using NADH.
Where does glycolysis occur within the eukaryotic cell?
the cytoplasm Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
How does glycolysis occur in eukaryotes?
In both the prokaryotic as well as eukaryotic cells, the process of glycolysis takes place in the cytoplasm. This process is anaerobic as it does not require oxygen. Glycolysis is the one of the primary metabolic pathways involved in cellular respiration that results in the formation of ATP which is a form of energy.
Where does Calvin cycle occur in C3?
the chloroplast Calvin cycle is also known as the C3 cycle. It is the cycle of chemical reactions where the carbon from the carbon cycle is fixed into sugars. It occurs in the chloroplast of the plant cell.
