Complete question:

A. With an input of energy, ADP rearranges to become ATP.

B. Without any energy change, ADP rearranges to become ATP.

C. With an input of energy, ADP combines with a phosphate group to become ATP.

D. With a release of energy, ADP combines with a phosphate group to become ATP.

Explanation:

C. With an input of energy, ADP combines with a phosphate group to become ATP.

In respiration, energy is released when a phosphate group is removed from ATP; ATP is formed from the phosphorylation of ADP with an inorganic phosphate, Pi, which forms an unstable, high energy phosphate bond.

ADP + inorganic phosphate (Pi) + energy → ATP

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate through the process of glycolysis in the cytoplasm).

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water- a process called chemiosmosis.

Glucose molecules bond together in a process known as dehydration synthesis. What happens in this process?

qaws [65]

Answer:

In the dehydration synthesis reaction above, two molecules of the sugar glucose (monomers) combine to form a single molecule of the sugar maltose. One of the glucose molecules loses an H, the other loses an OH group, and a water molecule is released as a new covalent bond forms between the two glucose molecules.

2. What is formed when elements of matter are chemically combined?

Lelu [443]

Answer:

Option B. compounds

Explanation:

Compound is a type pure substance which is formed when two or more than two elements combine together chemically in a fixed ratio. It is represented by a chemical formula. Chemically combine means the elements present in the compound make bonds in order to hold each other. So they are not separated by physical methods. It is separated from one another by chemical methods.

Taya2010 [7]

DNA uses deoxyribose, while RNA uses ribose. DNA is double-stranded, RNA is single-stranded. DNA is helical (spiraled), while RNA generally isn’t. DNA’s bases include thymine but not uracil, while RNA’s bases include uracil, but not thymine.
