3. Type of Receptor That a Typical Steroid Binds

1. When a ligand binds to a receptor, this level of protein structure is changed in the structure of the receptor

Tertiary

2. binding of a signaling molecule ( a ligand) to two receptor tyrosine kinases causes them to dimerize (bine together). This causes a conformational change in the receptor proteins that activate the intracellular enzymatic domains whose function is to add phosphate groups to another molecule. These domains or specific enzymatic areas are called….

Kinases

3. type of receptor that a typical steroid binds

intracellular

4. After a first messenger binds to a G-protein receptor, this will lead to activation of this enzyme

Phospholipase C

5. Once activated, Phospholipase C cleaves PIP2 into DAG and IP3. IP3 will diffuse into the cytosol and bind to gated channels in the ER, causing channels to open and ______to diffuse into the cytosol

6. Every virus has a nucleic acid genome (may be ss or ds RNA or DNA) and this

Capsid

7. Type of phage life cycle that results in death of the host cell

Lytic cycle

8. Type of phage life cycle that does not kill the host cell. The phage genome is integrated into the host genome to make a prophage, which is copied with the host cell genome during each cell division.

Lysogenic cycle 9. Sugar which are covalently bound to a polypeptide, are on the outer membrane (envelope) of most viruses that infect animal cells

Glycoprotein

10. process where 4 haploid cells are made from 1 diploid cell

meiosis

11. Process where 2 diploid cells are made from 1 diploid cell

Mitosis

12. Term for when multiple sperm enter an egg

Polyspermy

13. Term for when a diploid nucleus is injected into a enucleated (nucleus removed) oocyte (egg)

Somatic nuclear transfer

14. Influenza viruses have two types of glycoproteins, neuraminidase (NA), and ______

Hemagglutinin (HA)

15. This is an enzyme that transcribes dsDNA from ssRNA. HIV must have it in order to effectively invade a host cell and integrate into its’ genome

Reverse transcriptase

16. This is another enzyme that also uses RNA as a template to make DNA

Telomerase

17. This is a type of drug that targets bacteria

Antibiotic

18. a group of cells organized to carry out one or more specific function

Tissue 19. type of vascular tissue that conducts water and minerals upwards from roots to shoots

20. type of vascular tissue that transports sugars from photosynthetic tissues to where they are needed

phloem

21. pathway for water transport from a root hair to the xylem that goes from cytosol to cytosol connected by plasmodesmata

symplast

22. an organ that produces more sugar than it requires

source

23. an organ that consumes more carbohydrate/sugar than it can produce

24. type of phloem cell that doesn’t have nuclei and organelles

sieve tube element

25. term for how growth and pattern formation continues throughout the life of the plant

indeterminate growth
