How would treatment of cells with a drug that makes membranes permeable to protons affect the function of the lysosomes?

The basis for skeletal muscle contraction is the?

What distinguishes the functions of smooth endoplasmic reticulum (SER) from peroxisomes?   A) SER is primarily involved in lipid metabolism, while peroxisomes are responsible for protein synthesis. B) SER plays a role in detoxification processes, while peroxisomes are involved in the breakdown of fatty acids and hydrogen peroxide. C) SER stores calcium ions for muscle contraction, while peroxisomes regulate pH balance within the cell and breakdown of fatty acids. D) SER synthesizes carbohydrates for energy production, while peroxisomes store genetic material for cell replication

mRNAs are degraded in the cytoplasm by?

Which protein(s) link the nuclear lamina to cytoskeletal filaments?

The Calvin cycle is involved in the synthesis of _______ from _______.

What would be the result if a failure of the spindle assembly checkpoint allowed anaphase to initiate while one chromosome was attached to microtubules from only a single centrosome?

Cellulose?

You are studying a transporter found only in the apical plasma membrane of epithelial cells. You treat the epithelial cells with a synthetic peptide that is similar to the extracellular domain of a tight junction protein. The transporter is now found in both the apical and basolateral domains of the plasma membrane. What is the most likely mechanism by which the peptide disturbs the localization of the transporter?

How would inhibition of the APC/C ubiquitin ligase affect cells in mitosis?
