Answer:

Fe2+ atom has a larger size than Fe3+.

Explanation:

The electron transport chain is important for the production of the ATP molecule. The oxygen molecule acts as the final electron acceptor in the electron transport chain.

The size of the cation is always small as compared with the parental atoms. Two electrons are removed from Fe2+ and three electrons are removed from  Fe3+. This removal of electron increases the attraction force between the electron of the outermost shell and the nucleus and decreases the repulsion force between the electrons and thus decreases in size.

I’m which part of the cell is the majority of the energy released from breakdown of glucose
poizon [28]

Sentence Correction: In which part of the cell is the majority of the energy released from the breakdown of glucose?

nucleus

mitochondrion

cytoplasm

plasma membrane

Answer: <em>The answer is mitochondrion.</em>

Explanation: <em>The reason the is the correct answer is because, there are the Locations of Cellular Respiration which occurs in two stages.</em>

<em>First stange - cytoplasm</em>

<em>Second stage - mitochondrion</em>

<em>So as we can see, mitochondrion is the Second stage which is the correct answer because the majority of the energy released from the breakdown of glucose.</em>

When specialized cells are grouped together to form a common function, what they are called?
pishuonlain [190]
The answer to this question would be the last one, tissue.

These specialized cells group together to form a common function which then becomes a tissue. These tissues then group together and form an organ. Organs then form together a system and systems form together an organism. These organisms gather and form a community and eventually into an ecosystem. This is typically a process as to how cells become organisms and how organism make up the ecosystem. Cells are the basic unit of life. Without them, there would be nothing at all.

Please answer quickly!! Timed test! Which term is correctly paired with its role in the body? A) Insulin – a sugar that regulate
Nataly [62]

Answer:

The correct answer is -  D) Glucose – a sugar found in blood that can be broken down to produce ATP

Explanation:

Insulin is a hormone produced by the beta cells of pancrease that takes up the glucose from the bloodstram and make gucose available to the cells of the body to produce energy by the process of cellular respiartion. Glucose is breaken down to its smaller units and produced high amount of energy in the form of ATP. Glycogen is form of sugar that is stores in the muscle and othe cell for the energy in abscence or low glucose level in blood stream. ADP is a molecule know as adesnosine pyrophosphate or diphosphate which is play role in flow of energy. ADP molecules requires energy to form ATP molecule and when ATP splits into ADP and Pi releases high amount of energy.
