What is the largest organelle in a plant cell? What is a plant cell organelle that processes energy? What is the organelle of the cell called where a cell produces cell membrane? What organelle is most active in causing programmed cell death? a. nucleus b. lysosome c. rough ER d. centri...
Dietary mono-unsaturated fatty acids (MUFAs) are linked to longevity in several species. But the mechanisms by which MUFAs extend lifespan remain unclear. Here we show that an organelle network involving lipid droplets and peroxisomes is critical for MUF
The limit of fast transport implies that molecules move into and out of the the cell much more frequently than they are involved in reactions. The molecules are uniformly distributed in VT under these conditions, so that the probability that a randomly chosen molecule is in VC is simply \(\...
What is the more complex cell type that has a membrane-enclosed nucleus and organelles that carry out the functions of the cell? What is a selectively permeable membrane? (Also called a semi-permeable membrane) What is a dense organelle present in most eukaryotic cells called? It is typically...
the cell’s genetic material is kept within a membrane-bound nucleus, the cell’s energy production takes place inside an organelle called the mitochondrion, and photosynthesis in plant cells is restricted to plastids. This proper compartmentalization of the different biological functions is crucial for...
C. protein molecules cannot exit through the cell membrane. D. calcium ions block Na^+ and C What do we call the cell membrane of a muscle cell? The cell membrane: a. is the last part of the cell to be affected by the extracellular environment. b. separates the intracel...
The observation that WHAMM also localizes along tubulo-vesicular structures raised the possibility that it associates with membrane transport intermediates that move between the ER and Golgi. One organelle that is situated close to the Golgi and also in peripheral tubules is the ER-Golgi intermediate...
Biochemical assays to determine what the potential substrates of these molecules are, if any, will be important to understand their function. As the number and expanse of ciliopathies and associated genes increases, it will become increasingly important to do genome, or ciliome-wide screens to ...
For turns at the tip, this can be explained by the spatial orientation of the tip that is not in the same focal plane as the rest of the cilium, therefore making it impossible to detect single molecules around the tip in these experiments. This out-of-focus effect is less of a problem...
