Answer:

Pepsin is the gastric enzyme that initiates protein digestion.

The pepsinogen is first produced by the stomach lining. This is the inactive form. It reacts with is the stomach acid ( dil Hcl) to form pepsin(active form).

The ducts in the pathway by which pancreatic juice flows from the pancreas to the duodenum is the pancreatic duct

The Amino acids formed from the breakdown of Protein helps in the synthesis of enzymes, hormones and other biological cell components.

Amino helps in the replacement of worn out tissues.

It also helps in mental development and reduction of fatigue.

What is true about the function of the electron transport system (ETS)?
FrozenT [24]

The correct answer is the last option.

The first option does not make sense as the electron transport chain makes the most ATP from the whole ATP synthesis cycle including glycolysis and the Kreb's Cycle. It also does not make NADH, but instead splits NADH into NAD- and H+. The H+ are used later to make ATP.

The second option also does not make sense as a "lysosome" is a digestive "pocket" in the cell, used for taking in and digesting food for the cell.

The third option also does not make sense as it does not produce NADH and is not during glycolysis. The electron transfer chain breaks up NADH and FADH2 and is the last step in the ATP synthesis process, after glycolysis and Kreb's Cycle.

The last option is correct. The electron transfer chain has the ability to make 34 molecules of ATP (in theory; so in real-life this does not always happen). The electron transfer chain does break down several compounds derived from glucose in a series of chemical reactions that do occur in the cristae of the mitochondrion.

Zepler [3.9K]

20 ATP is the predicted energy yield from the Krebs cycle per molecule of glucose in eukaryotic cells.

In general oxidation of one molecule of NADH leads to the synthesis of three molecules of ATP whereas oxidation FADH2 yield only two ATP molecule .

ATP synthase is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP synthase is the enzyme that makes ATP by chemiosmosis. It allows the transfer of protons through the membrane using the kinetic energy to phosphorylate ADP making ATP.  ATP synthesis by chemiosmosis occurs in chloroplasts and mitochondria as well as in some bacteria.

tino4ka555 [31]
The statement above is TRUE.
The osteon is the fundamental functional unit of a compact bone. Osteons are roughly cylindrical in shape and they are typically several millimetre long and about 0.2mm in diameter. The osteon resembles the growth ring of a tree trunk.
The cylindrical structure of osteon is made up of four different parts which are a central tube, a lamellae, a lacunae and canaliculi.
