Answer:

D (proteins moving ions from low to high concentration across a cell membrane)

Explanation:

Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy. Hope you found this helpful! :)

Catabolic processes involve degradation of complex molecules into simpler molecules with the net release of?

Scrat [10]

Complex molecules are broken down into smaller molecules during catabolic processes, which results in a net release of chemical energy.

Complex molecules are broken down into simpler ones through catabolic processes, which often result in energy release. In catabolic processes, energy held in the bonds of complex substances, such as glucose and lipids, is released.

There are two main branches of metabolism: the catabolic (or energy-producing) branch and the anabolic (or energy-using) branch. Catabolism is the destructive branch, which produces energy. Larger, more complex molecules are broken down into smaller, simpler molecules in catabolic processes, which release energy in the process.

Mashcka [7]

Answer:

Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.

Which word identifies the agent that carries the energy released from earthquakes?

Mnenie [13.5K]

The correct answer is seismic waves.

A sudden movement of the Earth's crust followed by the production of seismic waves is known as an earthquake. The seismic waves travel outwards from the source. The sudden vibration or ground motion is generated due to a brisk discharge of accumulated energy.

The vibrations, which travel via Earth carrying the energy discharged at the time of an earthquake is known as seismic waves. The earthquakes are usually determined with a help of seismometer, called seismograph.

Consider the atps that can be generated via substrate-level phosphorylation. Will glycolysis be useful for generating any atps d

iris [78.8K]

Indeed, glycolysis would be useful for creating ATP as it produces a net increase of ATPs. One glucose particle produces two ATP in a cycle. On the off chance that the ETPUM experiences the procedure of aging, at that point the natural atoms would then be able to be used as the essential electron transporter. Two ATPs would be delivered by means of TCA cycle and yes it will be sufficient to help development.

Further Explanation:

Phosphorylation:

Phosphorylation is the synthetic expansion of a phosphoryl gathering (PO3-) to a natural atom. The expulsion of a phosphoryl gathering is called dephosphorylation. Both phosphorylation and dephosphorylation are done by catalysts (e.g., kinases, phosphotransferases).

ATP:

Adenosine triphosphate is an unpredictable natural synthetic that gives vitality to drive numerous procedures in living cells, for example muscle withdrawal, nerve motivation proliferation, and substance amalgamation. Found in all types of life, ATP is regularly alluded to as the "atomic unit of money" of intracellular vitality move.

ATP utilized for:

ATP Molecule. The Adenosine triphosphate (ATP) particle is the nucleotide referred to in organic chemistry as the "atomic cash" of intracellular vitality move; that is,ATP can store and move substance vitality inside cells.

TCA:

Tricyclic antidepressants (TCAs) are a class of drugs that are utilized basically as antidepressants. TCAs were found in the mid 1950s and were promoted later in the decade. They are named after their concoction structure, which contains three rings of particles.
