All living organisms break down sugar to obtain energy using cellular respiration, Which of the following chemical reactions rep
Ghella [55]

Answer:

The chemical reaction that represents the process of aerobic cell respiration is oxygen + glucose → water + carbon dioxide + energy

Explanation:

Cell respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions in which energy in the form of ATP molecules is obtained from a glucose molecule in the presence of oxygen.

<u>Glucose is the main energetic substrate</u> to be able to synthesize energy in the form of ATP, through oxidative phosphorylation. At the end of the process ATP is obtained as products, and as waste compounds water and carbon dioxide, which can be schematized in the following chemical reaction:

              <em>              C₆H₁₂O₆  +  6O₂ →  6H₂O  +  6CO₂ + ATP ↑</em>

<em>                Glucose + Oxygen → Water + Carbon dioxide + Energy ↑</em>

This reaction summarizes what happens in aerobic cellular breathing, which is necessary to synthesize energy for cellular functions.

The other reactions:

  • <em>oxygen + water </em><em>→</em><em> glucose + lactose </em>
  • <em>glucose + lactose </em><em>→</em><em> oxygen + water </em>
  • <em>water + carbon dioxide + energy </em><em>→</em><em> oxygen + glucose</em>

<em>do not represent the components or the order of the reactions that occur in aerobic cell respiration</em>

When recombinant DNA is inserted into the genome of a host organism, what's created? A. A genetic marker B. A restriction enzyme
PIT_PIT [208]

The answer is C.

Transgenic means that one or more DNA sequences from another species has been introduced by artificial means. For example, animals usually are made transgenic by having a small sequence of DNA injected into a fertilized egg or developing  embryo. Transgenic plants can be made by introducing foreign DNA into a variety of different tissues.

Most transgenic organisms are generated in the laboratory for research purposes. Others have been developed for commercial purposes  such as golden rice that has been modified to produce beta-carotene, the precursor to vitamin A.

The answer is microscopic life appeared on Earth before flowering plants. This is because according to the label on the second box, microscopic life appeared 4.0 to 3.5 billion years ago, and this is way before the date 250 to 120 millions years ago indicated on the label on the sixth box the flowering plants appeared on Earth.
