What is cellular respiration in AP biology?
Cellular respiration is the process that cells use to release energy from chemical bonds in food. The cell can then use this energy for the essential processes of life that require energy. It is possible for cellular respiration to be aerobic and anaerobic.
What are some questions for cellular respiration?
Cellular respiration test questions
- What is the name of the high-energy molecule used by cells?
- Glycolysis occurs in which part of the cell?
- During glycolysis, glucose is split into two molecules of what?
- If oxygen is not present, pyruvate molecules undergo what?
- The diagram shows the citric acid cycle.
Which of the following phases is not dependent on the presence of oxygen?
Glycolysis is the process that converts glucose to pyruvate. It produces a total of four ATP, but consumes two ATP, for a net yield of two ATP. Glycolysis is not dependent on the presence of oxygen and can occur in either aerobic or anaerobic environments.
Which phase of cellular respiration occurs in the cytoplasm whether oxygen is present or not?
glycolysis
Stage one of cellular respiration is glycolysis. Glycolysis is the splitting, or lysis of glucose. Glycolysis converts the 6-carbon glucose into two 3-carbon pyruvate molecules. This process occurs in the cytoplasm of the cell, and it occurs in the presence or absence of oxygen.
How do you test cellular respiration?
Measuring Respiration Scientists can measure the rate of cellular respiration using a respirometer by assessing the rate of exchange of oxygen. Understanding the Ideal Gas Law is of fundamental importance for knowing how the respirometer functions.
What is cellular respiration question and answer?
Answer: The sequence of reactions which converts glucose into pyruvic acid with the production of ATP is termed as glycolysis. It is a series of reactions in which 6 carbon glucose molecules converts into two 3 carbon molecules of pyruvic acid.
Can cellular respiration take place without oxygen?
Cellular respiration that proceeds without oxygen is called anaerobic respiration. After that, living things could use oxygen to break down glucose and make ATP. Today, most organisms make ATP with oxygen. They follow glycolysis with the Krebs cycle and electron transport to make more ATP than by glycolysis alone.
What are the main processes of cellular respiration?
– Glycolysis. In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. – Pyruvate oxidation. Each pyruvate from glycolysis goes into the mitochondrial matrix—the innermost compartment of mitochondria. – Citric acid cycle. – Oxidative phosphorylation.
What is cellular respiration Quizlet?
Define Cellular Respiration. The breaking down of organic compounds (glucose) so that energy is released, bit by bit. Where is energy stored. ATP molecule. What is required for cellular respiration and what is released. O2 is required. CO2 and H2O is released.
What is the oxidizing agent in cellular respiration?
– a small hydrophobic molecule, the only member of the electron transport chain that is not a protein – also individually mobile within the membrane rather than residing in a particular complex – also known as Coenzyme Q, or CoQ
What is the role of fermentation in cellular respiration?
Fermentation is another anaerobic (non-oxygen-requiring) pathway for breaking down glucose, one that’s performed by many types of organisms and cells. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end. Fermentation and cellular respiration begin the same way, with glycolysis.
