What are some questions about 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.
How do you answer AP Bio questions for free?
A few principles to remember when writing your AP® Biology free responses:
- Don’t restate the question.
- Write in complete sentences.
- If doing a calculation, make sure you clearly identify your final answer (this is most easily done by boxing your answer), AND show your work.
- Once you answer the question, move on.
How does the catabolism of glucose in glycolysis and pyruvate oxidation contribute to ATP synthesis?
Catabolism of glucose in glycolysis and pyruvate oxidation • Produces NADH for use in ETC • Produces acetyl-CoA for entry into Krebs cycle • Provides energy for (substrate level) phosphorylation of ADP Oxidation of intermediates in the Krebs cycle • Produces NADH or FADH2 for use in ETC • Releases high energy electrons …
Which of the following reflects a function of fermentation?
Which of the following reflects a function of fermentation? Explanation: Fermentation oxidizes molecules of NADH to NAD+ so the cell can have oxidizing agents for any subsequent glycolysis reactions. Fermentation leads to the production of ethanol in yeast cells and lactic acid in muscle cells.
What does cellular respiration produce?
ATP
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
What are some good questions to ask about photosynthesis?
Photosynthesis test questions
- What are the products of photosynthesis?
- What colour is chlorophyll?
- Where does photosynthesis take place?
- What are the reactants of photosynthesis?
- When do plants respire?
- When do plants photosynthesise?
- What are the cells near the top of leaves called?
- What does xylem carry?
What are free response questions?
Free response, usually referred to as essay, is a type of question used in tests in education, workplace, and government. Most free response questions ask or require the test-taker to state a belief, opinion, or write a short essay and support it with facts, examples, or other evidence.
How long is a free response essay?
one hour and 40 minutes
The free-response section lasts one hour and 40 minutes and consists of four questions, each of which is worth 12.5% of your total score.
What happens to excess energy in cellular respiration?
Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP. When excess ATP and glucose are present, the liver converts them into a molecule called glycogen, which is stored for later use.
Which process generates most of the ATP produced during cellular respiration?
electron transport chain
Explanation: The electron transport chain generates the most ATP out of all three major phases of cellular respiration. Glycolysis produces a net of 2 ATP per molecule of glucose.
Why does fermentation supply less energy than cellular respiration?
In the absence of oxygen, some organisms go through a process called fermentation, which allows them to produce energy under anaerobic conditions. Fermentation produces relatively less energy than respiration, because fermentation does not result in the complete oxidation of glucose.
What happens without cellular respiration?
Without the process of cellular respiration, there is no gaseous exchange and the cells, tissue and other organs die due to the lack of oxygen and by the accumulation of carbon dioxide within the cells and tissues.
What are the four phases of cellular respiration?
The four different phases of the cellular respiration process are: glycolysis, pyruvate oxidation, the citric acid cycle or Krebs cycle, and oxidative phosphorylation. Phases of cellular respiration detailed: Glycolysis , citric acid/Krebs cycle, electron transport chain.
What is a simple explanation of cellular respiration?
Cellular Respiration. A simplified approach to remembering cellular respiration is to break it down into 3 major steps and learn them separately.
What is the first stage of cellular respiration?
The first stage of cellular respiration is glycolysis, which is a set of ten reactions that do not require oxygen and hence occurs in every living cell.
What is cellular respiration is associated with?
Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water. Organisms that do not depend on oxygen degrade foodstuffs in a process called fermentation.
