Why must cells carry out cellular respiration?

Answer 2

Cells must carry out cellular respiration to generate ATP, which is the energy currency used for various cellular processes. Cellular respiration involves breaking down glucose to produce ATP through the process of glycolysis, the citric acid cycle, and oxidative phosphorylation. This process is essential for the survival and functioning of cells.

Answer 3

Cells perform cellular respiration to create ATP. ATP is the main energy source in a cell, which is used to carry out the cell's processes. Cellular respiration is when oxygen is used to convert the chemical energy in organic molecules in to ATP.

Answer 4

Cells carry out cellular respiration to convert carbohydrates, fats, and proteins to ATP. ATP acts as the "fuel" of the cell, providing energy for cellular processes such as transporting molecules in and out of cells.

The first step of cellular respiration is glycolysis. Glucose is converted into 2 pyruvates, resulting in a net yield of 2 ATP and 2 NADH (per glucose).

The second step is pyruvate oxidation. If oxygen is available, the 2 pyruvates enter the mitochondria through active transport (transporting the pyruvates results in a loss of 2 ATP). The 2 pyruvates are converted into 2 AcetylCoA. 2 NADH and 2 CO2 (per glucose) are also the products of pyruvate oxidation.

The third step is the Citric Acid Cycle/Krebs Cycle, which takes place in the matrix of the mitochondria. AcetylCoA enters the cycle and reacts with various molecules during the cycle. A net yield of 6 NADH, 2 FADH2, 2 ATP, and 4 CO2 (per glucose) is produced.

The fourth and final step is oxidative phosphorylation. NADH and FADH2 unload their electrons, and the energy from these dropped-off electrons is used to create a H+ gradient by pumping H+ ions into the intermembrane space of the mitochondria. The H+ ions diffuse back through ATP Synthase, an enzyme that creates 34 ATP (per glucose). The used-up electrons are transferred to O2 to produce 6 H2O (per glucose).

If no oxygen is available, fermentation is the second step after glycolysis. It regenerates NAD+ from NADH so that glycolysis can be repeated over and over again. There are two different types of fermentation: lactic acid fermentation and alcoholic fermentation.

Answer 5

Cellular respiration is one of the processes that cells perform. Organisms do not perform this process. Instead they perform respiration. Cells use cellular respiration to obtain one of the three sources needed for them to live- oxygen. Without this process, cells would not be able to perform other functions.

Answer 6

Cellular Respiration makes energy for the orangism.
