Answer:
The correct answer is "5-1-3-2-4".
Explanation:
Internalization of LDL particles into cells, is needed to form the intracellular vesicles known as endosomes. The order of events that allow for this process are:
5) LDL receptors migrate to the cell surface and cluster in clathrin-coated pits. Clathrin acts directing the receptors to the cell membrane region where endosomes are formed.
1) A combination of cholesterol and apolipoprotein binds to LDL receptors and becomes internalized as endocytotic vesicles. Once the receptors are in the proper cell membrane region, cholesterol and apolipoprotein are bound and internalized.
3) Several endocytotic vesicles fuse to form an endosome.
2) The environment of the endosome becomes acidic, which causes the LDL to dissociate from its receptor; additionally, the endosome fuses with a lysosome. LDL should be dissociated from its receptor since it is going to be degraded in the following step.
4) The LDL particle is degraded by the lysosome. This takes place after endocytosis, when LDL particles are transported into lysosomes once they are fused, cleaving the cholesterol esters into cholesterol and fatty acids.
Answer: Anterior cruciate ligament
Explanation:The anterior cruciate ligament (ACL) connects the front of the tibia to the back of the femur. It keeps the tibia from sliding forward and limits its rotation. The posterior cruciate ligament (PCL) keeps the tibia from sliding backward. The patella ligament helps secure the patella over the front of the knee joint.
Answer:
The water potentials (Ψ) of the cell and its surroundings are the same.
Explanation:
When a cell is kept in hypotonic surroundings such as distilled water, the osmotic movement of water occurs towards the cell. The entry of water makes the cell swell up and it becomes turgid. Water potential is determined by solute and pressure potentials mainly. Here, the solute potential of the cell and the distilled water was different resulting in differences in their respective water potential values which in turn served as a driving force for endosmosis.
When the cell is fully turgid, the solute concentration of the cell and the surrounding distilled water become equal to each other. Under these conditions, the water potential of the cell and distilled water are the same.
