Answer:
Small and lipid soluble cortisol can pass through nonpolar core of the plasma membrane.
Explanation:
Cortisol is a lipid-soluble steroid hormone with a compact structure. The plasma membrane is a bilayer of phospholipids.
The phospholipids are amphipathic molecules with a polar head and nonpolar tails. The nonpolar tails of the two layers of phospholipids are packed away from the watery medium and make the core of the plasma membrane.
Being a lipid-soluble hormone with a small structure, cortisol can pass through the nonpolar core of the plasma membrane easily to activate its receptors and alter the gene expression.
Answer:
. 2C- acetyl Co-A from the link reaction enters the kreb Cycle to combine with 4 Carbon Oxaloacetate to form 6- Citrate
The Citrate forms intermediate Isocitrate, which eventually formed 6-C alpha ketoglutarate.
The alpha-ketoglutarate forms the intermediate succinyl-Co A, which later formed 5C-succinate.
5C -Succinate forms 4C-fumarate, the latter formed 4C-malate- which eventually formed 4C-oxaloacetate.
The 4C of these compounds is fixed, to ensure constant availability of 4C of oxaloacatate for 2C Acetyl -CoA to bind it for the cycle to continuously occur for production of first product Citric Acid from which other products are formed from.
Explanation:
Answer:
A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.
Answer:
<u>vacuole</u>
Explanation:
Vacuoles are filled with cell sap which contains sugar, salts and waste products and enclosed by tonoplast, a membrane. They mostly act as a store for sugars and salts, they maintain the shape of the cell and play a role in osmoregulation. They are found in both plant and animal cells.
