Digestion includes breaking substances into their simpler building blocks, synthesizing more complex cellular structures from si
kicyunya [14]

Answer:

The correct answer is - false statement.

Explanation:

The statement mentioned in question explaining the process of metabolism. Metabolism is a procedure that includes catabolic and anabolic process that which are chemicals reactions takes place in the body. Metabolism is breaking large molecules into simpler and simpler molecules to synthesizing complex molecules from simpler molecules.

Digestion is the process in which ingested food break down to simpler substances and absorbed to provide nutrients to body.

Thus, the correct answer is - false statement.

_The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of
Hoochie [10]

Complete question:

The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K

  • True
  • False

Answer:

TRUE

Explanation:

The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.

Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.

Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.

K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.

Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.

Photosynthesis and respiration are alike in that
Natalija [7]
Both photosynthesis and respiration require specific catalyst.
Why not the other answer?
(1) only photosynthesis require the sun as a source of energy,respiration use glucose.
(2) photosynthesis result in the formation of glucose,respiration result in the formation of carbon dioxide.
(3)Only respiration occur in the mitochondria,photosynthesis occur in the stroma of the chloroplast.
Answer is 2 because both of them require specific enzyme and as you know enzymes are biological catalyst.
