6 0

The correct answer is :

Some substances but not other can cross the (blank ) membrane of a cell. The   blank is to be filled with either cell or plasma. Cell membrane or plasma membrane is the living boundary of a cell which is made of phospholipid. It is a semi-permeable or differentially permeable membrane. It only allows small and non-polar molecules to pass through it. It prevents polar ions or molecules to pass through it

If a cell is able to synthesize 30 ATP molecules for each molecule of glucose completely oxidized to carbon dioxide and water, a
nadezda [96]

Answer:

The correct answer is - 14 OR 15 ATP.

Explanation:

At the end of the glycolysis, two molecules of the pyruvate produced in the cytoplasm which is followed by the pyruvate oxidation that takes place in the matrix of mitochondria in eukaryotes.

During the oxidation of the pyruvate, a carboxyl group is eliminated from the pyruvate and released as CO₂. Then the two carbon molecules oxidized produced in the first step and NAD+ accepts the electron and change into the NADH. The oxidized two carbon molecules attached to the coenzyme A and form acetyl CoA. This process generates 1 NADH which is equal to the 3 ATP.

During the TCA cycle, each molecule of the acetyl CoA oxidized to generate ATP  and carbon dioxide. This cycle produces 1 ATP, 1 FADH2, and 3 NADH. The total ATP production through this cycle is Approximately 12.

Thus, the correct answer is - 14 or 15 ATP.

Explain why your weight in pounds is much lighter on the moon but your mass is the same? (Gravitational force on the moon is 1.6
schepotkina [342]

there's a mistake in the question, weight isn't measured in pounds its measured in newtons, mass is measured in pounds

im going to assume ur asking why our weight is different on the moon and earth, and why the mass remains the same

weight is how many newtons of gravity is acting on you. the gravitational field strength on earth and moon are very different. on earth its 9.8N and on the moon its 1.6N. Because the force of gravity is weaker on the moon, you weigh less.
