Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

Expert Solution & Answer

Explanation of Solution

The source of carbohydrates to our body is food. The food one ingests is digested firstly. The digestion is completed in the small intestine and monosaccharides like glucose are obtained. These are then transported (absorbed via microvilli) through blood to all the cells in the body that require it.

The glucose molecules undergo glycolysis in the cytosol to give pyruvate. Depending whether the respiration was aerobic or anaerobic, the pyruvate enters citric acid cycle (mitochondrial matrix) or fermentation (in the cytosol), respectively.

In fermentation, either lactate or ethanol is produced. Before the citric acid cycle starts, pyruvate is oxidized into acetyl-CoA. This then enters the citric acid cycle to yield molecules with high energy electrons. The molecules are used in electron transport chain in the inner mitochondrial membrane to generate a proton motive force. This positive force is used to generate ATP molecules by oxidative phosphorylation.

Conclusion

The main role of carbohydrates in living beings is energy production by cellular respiration.

Biology Question

✓ Details Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.
