The movement in phloem is bidirectional, whereas, in xylem cells, it is unidirectional (upward).
Answer:
a) the molecules can be found in the picture below
b) (i) isocitrate lyase ( isocitrate to glyoxylate)
(ii) malate synthase (glyoxylate to malate)
c) Glyoxylate cycle do no exist in animals
Explanation:
b) in the glyoxylate cycle isocitrate lyase helps in conversion of isocitrate to glyoxylate. Also, helps in conversion of glyoxylate to malate by using malate synthase.
c) Glyoxylate cycle do no exist in animals, it only exist in plants and bacteria. This is because they can produce glucose from acetyl-CoA in required amounts.They have the ability to change acetyl-CoA from fat into glucose. But in animals, this mechanism is not possible.
D. <span>They all contain carbon as an important part of their structure. Hope this helps you!! =')</span>
The complex of DNA and protein that makes up a eukaryotic chromosome is properly called <u>chromatin .</u>
<u></u>
- Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.
What is the chromatin and its function?
- To create chromosomes, chromatin fibers are coiling and condensing.
- Numerous cellular functions, including DNA replication, transcription, DNA repair, genetic recombination, and cell division, are made possible by chromatin.
What is chromatin in cell?
- Chromosomes in eukaryotic cells are made of chromatin, a compound of DNA and proteins.
- Nuclear DNA is extremely compressed and wrapped around nuclear proteins in order to fit inside the nucleus; it does not exist as free linear strands.
Where is chromatin found?
- Chromatin is a genetic material or a macromolecule comprising DNA, RNA, and associated proteins, which constitute chromosomes in the nucleus of a eukaryotic cell.
- This chromatin is located within the cell nucleus.
