Large amounts of adenosine triphosphate (atp) are generated when:

1 answer:

8 0

Large amounts of ATP are generated when the body cells function with adequate oxygen. ATP molecules are the energy currency of the cells; cells derived the energy they need for their activities from the metabolism of ATP molecules. ATP need oxygen in order to function maximally.

In the electron transport system

antoniya [11.8K]

Answer:

A. NADH and FADH2 both donate electrons at the same location.

Explanation:

In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.

These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.

Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.

NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.

The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields 34 ATP, however, under normal conditions an average of 26 ATP molecules is formed.

If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.

Answer:

Explanation:

Respiration can happen without sunlight,but photosynthesis cannot.and photosynthesis doesn't take place at night,so less carbon dioxide is used up than it is produced.

Match the givin changes in the ecosystem to their causes

poizon [28]

Answer:

The correct answers are:

1. Greenhouse gases: Earth's heat is kept from going away.

Greenhouse gases, particularly CO2 and methane, have properties that allow them to trap heat in the atmosphere. This means that the more of these gases there are in the air, it will be hotter on Earth.

2. Chemicals released into the river—unfit for human consumption.

The chemicals released into rivers pollute the water, making it unfit for human consumption. There are only a few places in the world where there is enough freshwater to go around, so the fact that so many rivers have been poisoned is very worrying.

3. Excessive agricultural land use—forest fragmentation.

People cut down the trees so that there is more land that can be used for farming, As a result of this process, forests are being destroyed to the point of total devastation, and it is likely that this percentage will rise in the coming years as things continue.

In granulocytes, what happens to the nucleus as the cell ages?

The granulocytes have been commonly recognised and distinguished histologically by their nuclear shapes and sizes. They contain multi-lobed nuclei, each lobe connected by a short region of nucleoplasm.
