What is the most likely result of damage to the Thlaykoid membranes in a plant?
Answer: Reduced glucose production due to decreased rate of photosynthesis. Explanation: Thylakoid membranes of chloroplasts in plant cells are site for light reactions of photosynthesis.
Which of the following would most likely happen if the ATP synthesis in the mitochondria?
If the ATP synthesis in the mitochondria of a plant’s cells suddenly operated poorly the plant cells would die because they wouldn’t extract enough energy from the glucose produced in photosynthesis.
Which of the following occurs in the cytosol of a eukaryotic cell?
Glycolysis normally takes place in the cytosol part of cells and it represents the first step in the cellular respiration process. The process of glycolysis yield two ATP and pyruvate, which is decarboxylated to form acetly coA that is used in the kreb cycle (Citric Acid Cycle).
Which process takes place in the cytosol?
Glycolysis occurs in the cytosol of the cell and does not require oxygen, whereas the Krebs cycle and electron transport occur in the mitochondria and do require oxygen. Cellular respiration takes place in the stages shown here. The process begins with a molecule of glucose, which has six carbon atoms.
Which process in eukaryotic cells will proceed normally whether oxygen is present or absent?
During which stages of cellular respiration is carbon dioxide released?
During which stages of cellular respiration are carbon dioxide molecules released? Carbon dioxide molecules are released during the transition phase and Kreb’s cycle.
What is the correct sequence of steps in cellular respiration starting with glucose?
What is the correct sequence of steps in cellular respiration, starting with glucose? Glycolysis, pyruvate processing, citric acid cycle, electron transport, oxidative phosphorylation. What is the last step of cellular respiration? You just studied 43 terms!
How many molecules of metabolic water are produced in glycolysis in the absence of oxygen?
Glycolysis Overview Glycolysis is a linear metabolic pathway of enzyme-catalyzed reactions that convert glucose into two molecules of pyruvate in the presence of oxygen or into two molecules of lactate in the absence of oxygen.
What happens to pyruvic acid in a plant cell if I oxygen is present in the cells II oxygen is absent in the cells?
Pyruvic acid supplies energy to living cells through the citric acid cycle (also known as the Krebs cycle) when oxygen is present (aerobic respiration); when oxygen is lacking, it ferments to produce lactic acid.
How much co2 is produced in glycolysis?
Does glycolysis give off co2?
Glucose ( 6 carbon atoms) is split into 2 molecules of pyruvic acid (3 carbons each). This produces 2 ATP and 2 NADH. Glycolysis takes place in the cytoplasm. This breaks down the pyruvic acid to carbon dioxide.
What is the 3 carbon product of glycolysis?
Glycolysis, as the name suggests, is the process of lysing glucose into pyruvate. Since glucose is a six-carbon molecule and pyruvate is a three-carbon molecule, two molecules of pyruvate are produced for each molecule of glucose that enters glycolysis.
What is the final product of ETC?
The end products of the electron transport chain are water and ATP. A number of intermediate compounds of the citric acid cycle can be diverted into the anabolism of other biochemical molecules, such as nonessential amino acids, sugars, and lipids.
What is the end carbon carrying product of glycolysis?
Pyruvate is the end product of glycolysis. After glycolysis, the three-carbon molecule pyruvate is converted into the two-carbon molecule acetyl-coenzyme A (acetyl-CoA). This is carried out by a combination of three enzymes collectively known as the pyruvate dehydrogenase complex.
Does alcoholic fermentation produce CO2?
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.
Which of the following are the 3 main products of glycolysis?
Glycolysis involves the breaking down of a sugar (generally glucose, although fructose and other sugars may be used) into more manageable compounds in order to produce energy. The net end products of glycolysis are two Pyruvate, two NADH, and two ATP (A special note on the “two” ATP later).
Does glycolysis produce water?
Glycolysis is the first of three stages of cellular respiration. Additionally, two molecules of water are created during this step, but they are a byproduct of the reaction and not used in the next steps of cellular respiration. It is not until later in the process that more ATP and water are created.
What is the most important step in glycolysis?
The most important regulatory step of glycolysis is the phosphofructokinase reaction. Phosphofructokinase is regulated by the energy charge of the cell—that is, the fraction of the adenosine nucleotides of the cell that contain high‐energy bonds.
How many water molecules are used in glycolysis?
two water molecules
How many water molecules are used in Kreb cycle?
2 water molecules
Is ADP formed in glycolysis?
In Summary: Glycolysis As ATP is used for energy, a phosphate group is detached, and ADP is produced.
How many water molecules are made in cellular respiration?
What is the final stage of cellular respiration?
Cellular Respiration Stage III: Electron Transport Electron transport is the final stage of aerobic respiration. In this stage, energy from NADH and FADH2, which result from the Krebs cycle, is transferred to ATP.
Where does the carbon dioxide come from that is produced during cellular respiration?
The Krebs cycle uses a 2-carbon molecule (acetyl-CoA) derived from pyruvate and produces carbon dioxide.
What gas is given during cellular respiration?
