What substance is the USABLE source of the energy that an animal cell uses for the synthesis of materials?

1 answer:

3 0

ATP because its essentially stored energy. All the cell has to do to release the energy is break off a phosphate. ATP is like money in the bank. It's there when cells need energy. Glucose is the preferred molecule to go through the krebs cycle to be made into ATP, but it has to be converted to ATP before its energy can be used. Starch is a macromolecule and has to be broken down into monosaccharides and then converted into ATP, so it's not he most direct source of energy. DNA is the code for telling the cells what proteins to make. It's not a source of energy. Sorry its long but hope it helps!!

When a pigment molecule in a light-harvesting complex absorbs a photon of light, what happens to its excited-state electron?.

MA_775_DIABLO [31]

When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.

It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll.
An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules.
An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.

Answer:

It is a good concept but can't be used.

Explanation:

Producing artificial blood is a good concept but it can't take the place of real human blood because the artificial blood has many disadvantages which can cause great damage to our body such as binds nitric acid that affected blood flow, increases the level of bilirubin, amylase and lipase in the blood and also cause overload of iron in your organs or tissues so that's why it can't be used instead of original human blood but may be in the future if these complications are removed.

Why does DNA look like a folded thread? HELP ME PLEASE!!!!

ololo11 [35]

Answer:

During DNA packaging, long pieces of double-stranded DNA are tightly looped, coiled, and folded so that they fit easily within the cell. Eukaryotes accomplish this feat by wrapping their DNA around special proteins called histones, thereby compacting it enough to fit inside the nucleus
