Cellular Respiration
Cellular Respiration is the series of metabolic reactions that takes place in a cell that harvests chemical energy. The energy is converted from the stored chemical energy in molecules to the stored energy in ATP.

Do panda bears use cellular respiration?
No, animals breath in oxygen and breath out carbon dioxide. Plants breath in carbon dioxide and breath out or release oxygen, this also includes algae which is a type of plant.
What is the similarity and the major difference between cellular respiration and photosynthesis?
photosnthesis is a process producers use to make theyre own food
- happens only in producers
- happens in chlorplasts
- only happens during daylight
requires:
- sun
- carbon dixoxide
- water
produces:
- sugar (glucose)
- oxygen
respiration is a process that consumers use to release energy from the food they eat
- happens in all living things
- begins in the cytoplasm & ends in the mitochondria
- can happen any time
requires:
- food (glucose)
- oxygen
produces:
- lots of energy
- carbon dioxide
- water
fermentation is a process that releases energy from food when ther is not enough oxygen for respiration to hapen
- happens in cytoplasm
- only happens in consumers
requires:
- food
produces:
- less energy
- lactic acid
- alcohol
- carbon dioxide
this process is also used to make bread, cheese, yogurt, and alcoholic beverages.
respiration is almost exactly opposite photosynthesis and the same as fermentation eccept fermentation doesnt use oxygen.
What reaction takes pace in the mitochondria and what are the reactants and products?
Mitochondria, is the part of the cell which converts oxygen into energy. It is the site of respiration in the cell and it produces energy so that the cell can carry out its basic functions. The end product it forms is ATP or Adenosine Tri-phosphate.
The red blood cells in our body do not have a mitochondria which ensures that the energy is transferred to the particular body part and is not absorbed by the RBC itself.
Which group of protist lack mitochondria?
- Microsporidia Giardia lamblia Entamoeba histolytica. Trichomonas vaginalis.
Which part of cellular respiration breaks down glucose into pyruvates?
This part of cellular respiration is called Glycolysis.
What happens to the high-energy electrons held by NADH if there is no oxygen present?
What happens to the high-energy electrons held by NADH if there is no oxygen present?
All the ATP in the electron transport chain and oxidative phosphorylation is produced by the enzyme ATP synthase enzyme which phosphorylate ADP with a phosphate by using the proton gradient across the membrane.
The organelle is mitochondria.
What molecule determines energy storage in cellular respiration?
Energy in glucose is released. That energy is stored in ATP
Why is photosynthesis and cellular respiration processes like two sides of a coin?
Photosynthesis make glucose and glucose is used by mitochondria. That is the reason
In order for cells to produce the MOST energy what gas should be present?
Oxygen to accept the electrons from the electron transport chain during oxidative phosphorylation.
Why water is expelled during glycolsis?
If you write this as a balanced chemical equation, water will form as a result. You must account, in other words, for all the elements.
Energized electrons are carried by NADH and FADH2 from glycolysis and the citric acid cycle to electron acceptors embedded in the cristae of the mitochondrion.
As electrons are shuttled along a chain of electron-accepting molecules in the cristae, their energy is used to pump accompanying protons (H+) into the space between mitochondrial membranes. This produces energy stored in ATP.
