1. What is cellular respiration? Cellular respiration is the process by which cells get their energy from food. It is a pathway where ATP is produced from the working cells.
2. What are the raw materials for cellular respiration? The raw materials are glucose and oxygen.
3. What is the simple reaction for cellular respiration? C6H12O6+6O2=6CO2+6H2O+Energy
4. Why is it not practical for an organism to release all of the energy in glucose at once? There wouldn’t be any energy left to repeat cellular respiration and create more energy.
5. List and briefly describe the events of the stages of respiration? Glycolysis is where glucose is split into two molecules of 3-carbon sugars. This produces 2ATP, 2 pyruvic acid, and 2 high energy. In The Citric Acid Cycle, Acetyl CoA is created. NAD and FAD are reduced carrying the high energy electrons to the next stage. In the Electron Transport, high energy electrons are passed to oxygen where ATP is then produced.
6. What are the three stages of cellular respiration in the correct order? Glycolysis, The Citric Acid Cycle, and Electron Transport.
7. What is released during cellular respiration? Energy stored in the chemical bonds of glucose.
8. How many molecules of ATP do you get from 1 molecule of glucose in cellular respiration? 28-30 molecules of ATP.
9. What part of cellular respiration occurs in the cytoplasm? Glycolysis
10. What is the net gain of ATP from glycolysis alone? 2 is the net gain of ATP.
11. What is the starting molecule for glycolysis? Glucose 6-carbon sugar
12. What are the two main types of fermentation?
Lactic acid fermentation and alcohol fermentation.

Glycolysis is the sugar splitting process where the molecule is split in half outside of the mitochondria. The molecule NAD+ picks up electrons and hydrogen atoms from the carbon molecule and become NADH. ATP is produced from the process, as well as pyruvic acid. Glycolysis can occur with or without oxygen. With oxygen it is the first stage of the cellular respiration, but if the process is done without oxygen it is called fermentation.…

Stage one glycolysis means the “splitting of sugar”. Glycolysis is a six carbon glucose molecule which is then broken in half, forming two three carbon molecules. The initial split requires an energy investment of two ATP molecules per glucose. Then the three carbon molecules donate high energy electrons to NAD+, the electron carrier forming NADH. Glycolysis then makes four ATP molecules when the enzymes transfer phosphate groups from fuel molecules to ADP. Glycolysis produces a net of two molecules of ATP per molecule of glucose. Then the pyruvic acid holds most of the energy of glucose and that energy is then harvested for stage two.…

1 Two critical ingredients required for cellular respiration are glucose and oxygen. Cellular Respiration, process in which cells produce the energy they need to survive. In cellular respiration, cells use oxygen to break down the sugar glucose and store its energy in molecules of adenosine triphosphate (ATP). Cellular respiration is critical for the survival of most organisms because the energy in glucose cannot be used by cells until it is stored in ATP. Cells use ATP to power virtually all of their activities—to grow, divide, replace worn out cell parts, and execute many other tasks. Cellular respiration provides the energy required for an amoeba to glide toward food, the Venus fly trap to capture its prey, or the ballet dancer to execute…

This cycle also called the “Krebs cycle”, completes the breakdown of glucose all the way to CO2, one of the waste products off cellular respiration. The enzymes for the citric acid cycle are dissolved in the fluid within mitochondria. Glycolysis and the citric acid cycle generate a small amount of ATP directly. They generate much more ATP indirectly, via redox reactions that transfer electrons from fuel molecules to NAD+, forming NADH.…

Cellular respiration is an ATP-producing catabolic process in which the electron receiver is an inorganic molecule. It is the release of energy from organic compounds by chemical oxidation in the mitochondria within each cell. Carbohydrates, proteins, and fats can all be metabolized, but cellular respiration usually involves glucose: C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 Kcal of energy/mole of glucose oxidized. Cellular respiration involves glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis is a catabolic pathway that occurs in the cytosol and partially oxidizes glucose into two pyruvate (3-C). The Krebs cycle occurs in the mitochondria and breaks down a pyruvate (Acetyl-CoA) into carbon dioxide. These two cycles both produce a small amount of ATP by substrate-level phosphorylation and NADH by transferring electrons from substrate to NAD+. The Krebs cycle also produces FADH2 by transferring electrons to FAD. The electron transport chain is located at the inner membrane of the mitochondria and accepts energized electrons from enzymes that are collected during glycolysis and the Krebs cycle, and…
