Answer:
45 %
In which 40 % by skeletal muscles.
Answer:
They provide a signaling molecule to begin the signal transduction pathway.
Explanation:
Brainliest!!!
Answer: All their offsprings will be heterozygous for both traits.
Explanation: The offsprings of this cross will be heterozygous for the two traits. Each the offspring will have one dominant allele and one recessive allele for both traits. All the offsprings will have a genotype of BbEe. B is a dominant allele and b is a recessive allele while E is a dominant allele and b is a recessive allele.
The answer should be letter B I'm sorry if not
Answer:
- multiple pathways
- ligands/signaling molecules
- inorganic phosphate
- inactive relay proteins
Explanation:
Receptor Tyrosine Kinase:
- Receptor tyrosine kinase (RTK) is the largest class of enzyme linked cell surface receptors.
- When a growth factor or a ligand binds to two neighboring RTK receptors, the two receptors bind together and form a dimer.
- This change in the conformation of the RTKs activates the associated tyrosine kinase enzymes.
- Tyrosine kinases break down ATP to ADP and phosphorylate the RTKs. Cross phosphorylation between the receptors helps activate multiple tyrosine kinases on the neighboring RTK.
- Once phosphorylated, the cytoplasmic ends of the RTKs are available for docking by relay proteins or signaling molecules with an SH-2 domain.
