During glycolysis, for every 6 moles of glucose that enter the pathway, how many moles of atp are used? how many moles atp are generated? how many moles of nadh are used? how many moles of pyruvate are made?

Answers

During the process of glycolysis 1 mole of glucose yields 2 pyruvic acid. In the process 2 ATPs molecules are used up and 4 other ATP molecules are produced by substrate level phosphorylation and 2 NADH are also produced. Therefore; for six moles of glucose; 12 ATP molecules will be used up, 24 ATP molecules will be generated, 12 moles of NADH will be used and 12 moles of pyruvate are made.

Which makes the phosphorus cycle different from the carbon cycles

Answers

The phosphorus cycle is different compared to the water,carbon, and nitrogen cycle because it can not be found in the gas state. Phosphorus is only found in land, water, and sediment. The phosphorus cycle is a bio-geochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. The other cycles is the process by which it is converted between its various chemical form. Phosphorus has small particles that only sometime go up into the atmosphere and contribute to acid rain but other than that phosphorus stays in and on land, sea, and sediment.(:

An ion that consists of 7 protons, 6 neutrons, and 10 electrons has a net charge of(I ) 4- (3) 3+(2) 3- (4) 4+

Answers

Answer : The correct option is 2.

Explanation :

Number of protons = 7

Number of neutrons = 6

Number of electrons = 10

Protons are those which carries positive charge.

Electrons are those which carries negative charge.

Neutrons are those which do not carry any charge that means neutrons are neutral.

The net charge on an ion = Number of protons present in an ion + Number of electrons present in an ion

The net charge on an ion = (+7) + (-10) = -3

Therefore, the net charge on an ion is (-3).

The answer is (2) 3-. The proton has one positive charge. Neutrons do not have charge. And electron has one negative charge. So the net charge is 3 negative charge.

Which of the following general statements about Earth's atmosphere is not true? a.Atmospheric scattering of light explains why our daytime sky is bright and blue.
b.The nitrogen and oxygen in Earth's atmosphere keep the surface pleasantly warm.
c.Even in low-Earth orbit, some atmospheric gas is still present.
d.Atmospheric pressure decreases with altitude.

Answers

Answer:

b.The nitrogen and oxygen in Earth's atmosphere keep the surface pleasantly warm.

Explanation:

Hello,

Based on the behavior of the Earth's atmosphere, it is widely known that the surface temperature depends on the altitude since the Earth's nucleus has the capacity to warm the outer surface as it is closer to it. In such a way, the warmness of the surface depends on the nucleus rather than the presence of nitrogen and oxygen.

Best regards.

Final answer:

Among the provided options, the statement falsely attributing the Earth's warmth to nitrogen and oxygen in the atmosphere is incorrect. It is the greenhouse gases that keep Earth's surface warm, not nitrogen and oxygen.

Explanation:

The statement that is not true among the options provided is option b. The nitrogen and oxygen in Earth's atmosphere do not keep the Earth's surface pleasantly warm. It's the greenhouse gases in the atmosphere, which include gases like carbon dioxide and methane, that trap heat from the Sun and keep the Earth's surface warm. Nitrogen and oxygen, which make up the majority of the Earth's atmosphere, do not have this property.

Other statements are correct. Scattering of light by the Earth's atmosphere does cause the blue colour of the sky (a), atmospheric gas is still present even in low-Earth orbit (c), and atmospheric pressure indeed decreases with altitude (d).
