What metabolic stage is part of fermentation and cellular respiration?
Glycolysis. In fermentation, glycolysis is the primary means by which energy is created. In cellular respiration, glycolysis creates pyruvic acid, which then enters the mitochondria and is further processed to create more ATP. Note, glycolysis is not a very efficient means of creating ATP (the primary source of energy in cells). Glycolysis only creates two ATP, while cellular respiration can create as much as 38.
How much ATP does it cost to run cellular respiration?
For cellular respiration two ATP must be put into glycolysis which starts the whole process of cellular respiration Steps: 1. Glycolysis 2. Transition Stage 3. Kreb cycle 4. Electron Transport Chain (ETC)
How much ATP are needed to fuel the process of cellular respiration?
Starting with Glycolysis, 2 ATP are required to start. 4 ATP are produced by the end of Glycolysis, with a NET ATP of 2.
Why is cellular respiration more efficient when oxygen is present in cells?
Without oxygen - only glycolysis occurs. This results in very few ATP molecules. With oxygen, all of celluar respiration occurs and this results in almost 40 ATP molecules. So, oxygen is essential to the production of mass ATP molecules.
In the first stage of respiration how much energy is released?
In the first stage of respiration, known as glycolysis, a small amount of energy is released. Specifically, glycolysis produces a net gain of 2 ATP molecules per glucose molecule broken down. Additionally, it generates 2 NADH molecules, which can be further utilized in later stages of cellular respiration to produce more ATP. Overall, glycolysis is an anaerobic process that occurs in the cytoplasm and serves as the initial step in energy extraction from glucose.

Why is cellular respiration consdered to be so much more efficient than glycolysis alone?
Glycolysis alone only nets you two ATP. Cellular respiration will net you an additional 34-36 ATP.
What process begins cellular respiration and does it produce much ATP?
Cellular respiration begins with glycolysis, which occurs in the cytoplasm of the cell. While glycolysis itself produces a small amount of ATP, a much larger amount of ATP is produced in subsequent stages of cellular respiration, such as the citric acid cycle and oxidative phosphorylation.
How much ATP does it cost to run cellular respiration?
For cellular respiration two ATP must be put into glycolysis which starts the whole process of cellular respiration Steps: 1. Glycolysis 2. Transition Stage 3. Kreb cycle 4. Electron Transport Chain (ETC)
What are two ways a cell can get energy from food?
Cells can release energy in two basic processes: Cellular respiration and fermentation. Cellular respiration requires oxygen but fermentation does not. Cellular respiration releases MUCH more usable energy then fermentation does.
What is the forms of cellular respiration?
There are anaerobic and aerobic types of cellular respiration. Anaerobic (including glycolysis) respiration does not involve oxygen. Aerobic (including the Kreb's, or citric acid, cycle and oxidative phosphorylation) respiration requires oxygen, and generates much more energy than anaerobic respiration.
How much ATP are needed to fuel the process of cellular respiration?
Starting with Glycolysis, 2 ATP are required to start. 4 ATP are produced by the end of Glycolysis, with a NET ATP of 2.
Why is cellular respiration considered to be much more efficent than glycolysis?
Because enzymes act as barriers in reactions making it more prone from sickness.... welcome

Which process takes place in the presence of oxygen and produces nearly twenty times as much ATP as glycolysis alone?
Aerobic respiration takes place in the presence of oxygen and produces nearly twenty times more ATP than glycolysis alone. It involves the Krebs cycle and the electron transport chain to effectively extract energy from glucose.
In the first stage of respiration how much energy is released?
In the first stage of respiration, known as glycolysis, a small amount of energy is released. Specifically, glycolysis produces a net gain of 2 ATP molecules per glucose molecule broken down.

Overall, glycolysis is an anaerobic process that occurs in the cytoplasm and serves as the initial step in energy extraction from glucose.
How much does ATP cellular respiration generates?
Anaerobic cellular respiration generates a net gain of 2 ATP. Aerobic cellular respiration generates 36 to 38 ATP.
