Unlike kinesins, dyneins are not directly attached to their target cargo molecules. They instead use a protein complex cofactor to bind and transport cargo molecules. What is the name of this protein complex? briefly explain it and the components

What is the exact function of loop of henle.

What key ATPase is important for maintaining this positive (outside) and negative (inside) transmembrane potential?

Consider the amino acids on the image below. Which of the following amino acids would be most likely to be found in the part of an integral membrane protein that is located within the membrane? (Select all answers that apply.) Asparagine (Asn)   Lysine (Lys)   Phenylalanine (Phe)   Valine (Val)   Glutamic acid (Glu)  Methionine (Met)

Identify the structures and functions of microtubule-based motor proteins, kinesins and dyneins.

Which of the following about Kinesin is FALSE? Kinesin is a dimer Kinesin is the (-) to (+) motor Kinesin walks along microtubules towards the nucleus O Kinesin uses ATP to move

What are the three types of coated vesicles involved in membrane trafficking. Name three types and briefly explain their role in the transport of material

Which of the following statements regarding kinesin are TRUE? (More than one answer is correct) Group of answer choices The majority of kinesin family members move along microtubules toward the (-) end Differential affinity of ATP- and ADP-bound kinesin for microtubules is important for kinesin walking The coiled-coil structure that links the two myosin motor proteins unwind after each step, requiring kinesin to periodically pause during transport and reenergize using ATP hydrolysis Kinesin movement is reminiscent of an inebriated individual walking (and carrying a balloon!)

What are the enzymatic activities of the sodium-potassium ATPase (pump)?     binds to and hydrolyzes ATP; binds to 3 Na+ in cytoplasm and releases outside cell; binds to 2 K+ outside cell and releases into cytoplasm     binds to and hydrolyzes GTP; binds to 3 Na+ in cytoplasm and releases into nucleus; binds to 2 K+ inside cell and releases into lysosome     binds to and hydrolyzes 3 ATP; binds to 1 Na+ in cytoplasm and releases outside cell; binds to 1 K+ outside cell and releases into cytoplasm     binds to and hydrolyzes ATP; binds to 2 Na+ in cytoplasm and releases outside cell; binds to 3 K+ outside cell and releases into cytoplasm

In addition to vitamin A (retinoic acid), which other fat-soluble vitamin has been shown to make lysosomal membranes more unstable and vulnerable to rupture (when the cytosol is acidic)? vitamin E (in the form of a-tocopheryl succinate) vitamin B12 (in the form of cyanocobalamin) vitamin C (in the form of ascorbic acid) vitamin B2 (in the form of riboflavin) vitamin B1 (in the form of thiamine)
