Energy accounting of aerobic respiration

In glycolysis there is a direct yield of two ATP molecules per degraded glucose molecules. Two NADH 2 molecules are also formed which, in the respiratory chain, provide energy for the synthesis of six ATP molecules. During the Krebs cycle, the two Acetyl-CoA molecules lead to the direct production of two ATP molecules.

The foundations in our daily life

Some bases are found in the substances used in our daily lives: magnesium hydroxide (Mg (OH) 2), present in the milk of magnesia used to combat stomach acidity; hydrated lime (Ca (OH) 2), used as mortar in construction; sodium hydroxide (NaOH), used for material cleaning, pipe unclogging and widely used in industry; ammonium hydroxide (NH 4 OH), a component of several commercially available cleaners.

Segmentation

The divisions that occur during segmentation are called cleavages, and the cells that form are called blastomers. In the Animal Kingdom, the difference in the quantity and distribution of calf in the egg determines differences in segmentation, the lower the rate of division. Because of this, we can consider two basic types of segmentation: holoblastic or total that occurs in the whole zygote; meroblastic or partial, which occurs only in part of the egg.
