Which would not be found in pancreatic juice secreted into the duodenum?
AURORKA [14]

Answer:

The answer is insulin.

Explanation:

Pancreatic juice is an enzyme containing secretion produced by the pancreas into the small intestine. Enzymes in the pancreas help in digesting proteins, carbohydrates and fats. The constituent enzymes are as follows:

  1. Trypsinogen and Chymotrypsinogen: Precursors of the proteases, trypsin and chymotrypsin that digest proteins. They are released as precursors to protect the intestinal lining. Enterokinase, an enzyme secreted by small intestine's epithelial cells, activates these precursor.
  2. Lipase: Enzyme that digests lipids by hydrolysing triglycerides into 2-monoglyceride and two free fatty acids.
  3. Amylase that helps in digesting any left over carbohydrates and complex starch.

Insulin:

Insulin can never be part of pancreatic juice because it is a hormone, not an enzyme. Hormones are chemical messengers secreted only in blood. Insulin is a hormone secreted by the pancreas to lower blood glucose levels by binding to insulin receptors on cells and stimulating the intake of glucose through glucose transport channels (GLUTs) in the cell membrane.

Roughly how many more atp’s can be produced via the complete aerobic oxidation of glucose compared to that produced by glycolysi
Lubov Fominskaja [6]

Roughly 15 times more ATP can be produced via the complete aerobic oxidation of glucose compared to that produced by glycolysis alone.

<h3>What is Glycolysis?</h3>
  • The metabolic process known as glycolysis turns the sugar glucose (C6H12O6) into pyruvate (CH3COCO2H). The high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process (NADH).
  • A series of ten enzyme-catalyzed processes make up glycolysis. the binding energy of carbs is captured. One metabolic route that doesn't require oxygen is glycolysis (In anaerobic conditions pyruvate is converted to lactic acid).
  • Glycolysis occurs frequently in various species, which suggests that it is an old metabolic route.
  • In fact, the events that makeup glycolysis and its companion process, the pentose phosphate pathway, take place in the oxygen-free environment of the Archean oceans, likewise in the absence of enzymes, and are catalyzed by metal.

What is an advantage of the mutualistic relationship between angiosperms and animals?
S_A_V [24]

Answer:

Refer below.

Explanation:

It is a beneficial species types association. The two life forms in the relationship profit by it. This typically happens in light of the fact that every living being needs something different has, so they can exchange.

Flowers that require fertilization are in a mutualistic relationship with the insects that fertilize them. The bloom gives nectar to the bugs to eat, and the creepy crawlies fertilize the blossoms.

The response of plants to periods of light and dark is called ______________. photoperiodism nocturnal variation daily activity
Alex73 [517]

Answer:

Photoperiodism

Explanation:

The term "photoperiodism" was coined to describe a plant's ability to flower in response to changes in the photoperiod: the relative lengths of day and night. Because flowers produce seeds, flowering is crucially important for the plant to complete its life cycle.
