What is the name of the pathway that begins cellular respiration?
The first step in cell respiration is glycolysis. It occurs in the cytoplasm and breaks down glucose into pyruvic acids.
Do plants need oxygen for their growth and development?
yes they perform cellular respiration too to get energy for themselves! therefore they need oxygen in the last step on cellular respiration to form ATPs
What is the final stage of aerobic respiration?
Glycolysis --> Pyruvate Oxidation --> Krebs Cycle--> Electron Transport Chain
What is the effect of arsenic on cellular respiration?
It prevents the protons (H+) from moving back into the inner membrane of the mitochondria from the proton gradient. Thus, proton trasnport is prevented.
Is the electron transport part of cellular respiration?
Yes, it's ultimate goal is to produce ATP (adenosine triphosphate), and its end product is a oxygen molecule which then combines with a free floating hydrogen proton to form H2O. The H2O is what is used to start the process of photosynthesis over again because that is where the electron particle comes from to aid in making NADPH (energy).
Which stage of cellular respiration requires oxygen?
The electron transport chain. Oxygen is the last electron acceptor.

What is needed for cellular respiration?
OXYGENIt is the last electron acceptor. It reduces into water
Where is the last three stages of cellular respiration?
There are three main stages of cellular respiration: 1) glycolysis, 2) Krebs Cycle, and 3) the Electron Transport Chain (ETC).
Where do NADH and FADH go to harvest their energy?
They enter the last stage of the Aerobic Respiration called the Electron Transport Chain (ETC).
Do plants need oxygen for their growth and development?
yes they perform cellular respiration too to get energy for themselves! therefore they need oxygen in the last step on cellular respiration to form ATPs
Are only 2 ATPs produced for each NADH molecule that enters the last stage of respiration?
The NADH molecule produces of 2 ATPs during the last stage of respiration. Some think that three ATPs are created from the NADH, however, the last stage of respiration is different than ATP and NADH during electron transfers.
What is the final stage of aerobic respiration?
Glycolysis --> Pyruvate Oxidation --> Krebs Cycle--> Electron Transport Chain
Does cellular respiration include oxygen?
Yes it is included.It acts as last electron acceptor.
What are the reactoants in cellular respiration?
Common substrate is glucose.O2 is used as last electron acceptor.
What is necessary for cellular respiration?
OxygenGlucose is the substrate. Oxygen is needed as last electron acceptor
What is the last stage of primary succession?
the last stage is called the last stage
