cell play a key role in the assembly of proteins. Chromosome - During cell division‚ DNA‚ the genetic material duplicates and forms linked coils called chromosomes. Endoplasmic reticulum - this organelle helps to transport materials through the cell. Rough reticulum is the site of attachment for ribosomes; smooth reticulum is the site of fat production. Nucleolus - this is a small structure inside the nucleus that plays an important role in ribosome production. Nucleus - this is the cells

Next‚ we have the Endoplasmic Reticulum which is like the airports boarding line. The boarding line moves items that are going to be boarded onto the plane. The Endoplasmic Reticulum does the same thing by moving items to different parts of the cell and serving as a pathway. Now we have the Golgi Apparatus which is kinda like the terminal. The Golgi

(DAG) and ceramides impair insulin metabolic signaling and prompt diabetic cardiomyopathy. In this regard‚ the increased DAG in cardiomyocytes impairs glucose metabolism through activation of protein kinase C (PKC) isoforms [24]. Ceramides are a family of bioactive waxy lipid molecules composed of sphingosine and a fatty acid [24]. Ceramide directly activates the atypical PKCs to phosphorylate and inhibit the insulin metabolic Akt/PKB signaling and thus inhibit GLUT4 translocation and insulin-stimulated

Biology 4U Exam Review Intro to Biochemistry Types of bonding: Ionic Results from the attraction between two oppositely charged atoms or molecules. They must lose or gain electrons to become charged. For example‚ a sodium molecule and a chlorine molecule form an ionic bond to create sodium chloride (NaCl) Covalent Results from the sharing of one or more pairs of valence electrons to create a stable molecule. For example‚ the covalent bonding of hydrogen ions creates hydrogen gas (H2)

breakdown of the membranes of these structures affect the function of Joseph’s heart cells? The breakdown of the membranes of these structures affect the heart’s function by causing calcium ATPase to cease moving calcium from the cytosol into the endoplasmic reticulum of Joseph’s cardiac muscle cells. The rise of calcium levels causes proteases to spill into the cell which attacks the cytoskeleton. D. Two important pieces of information – the instructions Joseph’s body needs to repair itself and his predisposition
