Which direction does Xylem flow? Phloem?

Biology
1 answer:
PIT_PIT [208]3 years ago
4 0

Answer:

The movement of Xylem is unidirectional and phloem is bidirectional

Explanation:

The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw.

Phloem transport is bidirectional because sucrose gets accumulated in the phloem tissue and absorbs water creating a high turgor pressure. ... Hence the water flows from regions of high turgor pressure to low turgor pressure and the direction can be upwards or downwards from the leaves based on the gradient.

One pyruvate molecule will generate _______ molecules of CO2 after completing the citric acid cycle
Rzqust [24]

Answer:

c) 3

Explanation:

Cellular respiration includes following 3 processes:

1) Glycolysis

2) Citric acid cycle or TCA or Kreb's cycle

3) Electron Transport Chain (ETC)

In glycolysis, a 3 carbon compound known as pyruvate is produced from glucose. Each glucose molecule produces 2 pyruvate molecules. Each pyruvate molecule then enters a complex known as Pyruvate dehydrogenase complex wherein the pyruvate molecule further undergoes oxidative decarboxylation to produce a 2 carbon compound known as Acetyl-CoA.

.

The Acetyl-CoA then enters citric acid cycle or TCA or Kreb's cycle wherein this Acetyl-CoA and oxaloacetate are oxidized to produce CO₂ molecules in eight steps. Each glucose molecule is capable of producing six CO₂ after the completion of citric acid cycle. Since one glucose molecule produces 2 pyruvate molecules then it means <u>a pyruvate molecule will be able to produce three CO₂.</u>
