Question

Cellular respiration is conducted by ana ocoonism The point of cellular respiration is to convert food in the form of Ceam into a difterent energy molecule (which can by used by celis) in the form of AAP Energy is needed to do work. What macromolecule does the work of the cel? need energy in the form of acidl s Therefore, so they can carry out life processes Aerobic celilular respiration means the CR process is using the molecule Humans, for example, conduct this type of CR. They gain the molecule by There are 4 major steps in aerobic cellular respiration Step One: In this step, the molecule which you obtain fromis down into two pieces. This occurs in the flocation). As a result, a few of the energy moleculeand the electron carrier are produced during step one Step Two: In this step, the carbon molecule produced from glycolysisgoes through a series of reactions. Primarily this occurs inside the molecule (which you exhale). Also produced is the electron carrier Step 3 In this step, the carbon molecule leftover from step two goes through a series of reactions. Primarily this occurs in the (organelle). During the process, the is produced and the molecule s produced as a byproduct (region) inside the (organelle) is produced as a byproduct (which you exhale). During the processes, the molecule Also produced are a few of the energy molecule Step 4 This step occurs along the uses the electron carriers and electron carriers and- It (region) inside the andproduced from steps 1-3. It also uses the molecule as a byproduct The main point of ?(which we inhale) which joins with H+ to produce, ? using an enzyme called this step, however, is to make many of the energy molecules

Explanation / Answer

Energy is needed to do work, what macromolecule does the work of the cell?

Carbohydrates, proteins, nucleic acids, enzymes etc.

DNA stores genetic information, while RNA are copies made to carry this information. RNA can be enzymatic too (ribozymes). DNA and RNA can't do their expected functions without the help of proteins. To make chromosomes, replicate DNA, copy DNA onto RNA, and to regulate the gene expression, various types of proteins are necessary (the proteins that work during DNA replication and transcription).

Carbohydrates are essential components of DNA and RNA (pentose sugars in the nucleotides). In addition, oligosaccharide chains serve as tags on many proteins and lipids for identification by other molecules. Cell surface is full of such tagged proteins and phospholipids. Energy (ATP) generation in cells to maintain all the cellular functions depends vastly on the availability of carbohydrates as the energy resource, making carbohydrates an essential part of cellular life.

Therefore, living organisms need in the form of ATP so they can carry out life processes.

Aerobic cellular respiration means the CR process is using the molecule Oxygen.

Humans, for example, conduct this type of CR. They gain the molecule by breathing (inhaling air).

Step one, GLYCOLYSIS

In this step, the molecule glucose which you obtain from food (carbohydrates) is broken down into two pieces. This occurs in the cytoplasm. As a result a few of the enerygy molecule ATP (four ATP molecules are created here) and the electron carrier NADH (two molecules of nicotinamide adenine dinucleotide, or NADH) are produced during step one.

Step two, pyruvate dehydrogenase reaction

In this step, the carbon molecule produced from glycolysis, pyruvate (three-carbon molecule), goes through a series of reactions. Primarily this occurs inside the mitochondria. During the process, the molecule Acetyl-CoA is produced and the molecule carbon dioxide is produced as a byproduct. Also produced is the electron carrier NADH.

Step three, Krebs Cycle

In this step, the carbon molecule leftover from step two goes through a series of reactions. Primarily this occurs in the matrix inside the  mitochondria. During the process, carbon dioxide ( two CO2 molecules per acetyl-coA molecule). Also produced are a few of the energy molecule ATP and electron carriers NADH and FADH2 (flavin adenine dinucleotide).

Step 4, Electron Transport Chain

This step occurs along the inner membrane inside the mitochondria. It uses the electron carriers NADH and FADH2 produced from steps 1-3. It also uses the molecule oxygen (O2) which joins with H+ to produce water H2O as a byproduct. The main point of this step, however, is to make the enerygy molecules ATP using enzymes called FO-F1 ATPase
