In the presence of oxygen, the three-carbon compound pyruvate can be catabolized in the citric acid cycle. First, however, the p
Flura [38]

Answer:1.

Explanation: This reaction is catalyzes by pyruvate dehydrogenase. Pyruvate being the end product of glycolysis has many fates after glycolysis,one of which is to enter the TCA(Tricarboxylic acid cycle) cycle. It is first converted to actetate by the action of pyruvate dehydrogenase. This enzyme converts pyruvate to acetate releasing CO2 and NADH because this oxidative decarboxylation of pyruvate is coupled with reduction of NAD+ which can feed into the electron transport chain.

Does changing the amplitude affect the period on a pendulum and how
yawa3891 [41]

Answer:

As the amplitude of pendulum motion increases, the period lengthens, because the restoring force −mgsinθ increases more slowly than −mgθ (sinθ≅θ−θ3/3!for small angles).

Examine the following isotopes of silicon (Si).
Vesnalui [34]

Answer:

They all have the same number of protons but different numbers of neutrons.

Explanation:

These are called isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.

The atomic number is the number of protons in an atom. For a neutral atom, it is the same as the number of electrons.

The mass number is the number of protons and neutrons in an atom.

silicon-28 (28Si)

silicon-29 (29Si)

silicon-30 (30Si)

All of these isotopes have an atomic number of 16

Now let us chech for the neutrons:

 Number of neutrons = mass number - atomic number:

for silicon-28 (28Si)  : 28-16 = 12 neutrons

     silicon-29 (29Si) :   29-16 = 13 neutrons

     silicon-30 (30Si):    20-16 = 14 neutrons.
