Anuta_ua [19.1K]

Answer

          The three metabolic pathways that make up aerobic respiration are really all parts of one larger pathway because the products of early pathways (like NADH) become <u>utilize</u> in the last one.

Explanation

         Aerobic respiration is that type of respiration in which glucose molecule is broken down into CO2 and H2O in the presence of oxygen and 36 or 38 ATP molecules are produced.

Aerobic respiration complete in four main steps:

1. Glycolysis

                  In this step glucose is broken down into 2 molecules of pyruvate acid along with the production of 2 ATP molecules and 2NADH.

2. Oxidation of pyruvate

                In this step pyruvate are oxidized in the presence of co-enzyme A to become Acetyl Co-enzyme A.  Again 2NADH are formed in this step.

3. Kreb Cycle

            It occus in mitochondria. Here acetyle coenzyme A enter Carbon fixation, reduction and regeneration phase. In this cycle 6 NADH, 2FADH2 and 2ATP are formed.

4. Electron transport chain

            All NADH that are produced in above steps get oxidize and help in the production of ATP along with the release of electron and proton that help in the formation of water.

Explain the term "Poly Inheritance" and give an example of a human trait that is controlled in such manner
Alenkasestr [34]

Answer:

Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Some examples include height, skin color, eye color and weight.

- In polygenic inheritance the "dominant" capital genes are additive, each capital gene adding one unit of color to the genotype.With more capital genes, the phenotype (appearance) gets darker.
