8.)-The vesicles and plasma membrane fuse, and the molecule is released to outside of the cell. Give four functions of a cells cytoskeleton -strengthens cell and helps maintain its shape -Supports cell's organelles such as RER, keeping them in position or moving them,...
- 《J Cell Sci Suppl》 被引量: 511发表: 1989年 The vacuolar H+-ATPase: a universal proton pump of eukaryotes. The vacuolar H+-ATPase (V-ATPase) is a universal component of eukaryotic organisms. It is present in the membranes of many organelles, where its proton-pum... ME Finbow,MA...
How many cell signaling pathways are there? What are membrane-bound organelles? What type of membrane protein is involved in passing ions and polar molecules across membranes? What are plant cell membranes made of? How many vacuoles are in an animal cell? How many mitochondria are in a stomac...
There’s an organism that changed the world. It caused the first mass extinction in Earth’s history … and also paved the way for complex life. How? Anusuya Willis explains how cyanobacteria, simple organisms that don’t even have nuclei or any other organelles, wrote a pivotal chapter in...
Cellular Respiration is the process of converting synthetic energy from food into a form that can be used in metabolism. In cellular respiration, the cell uses oxygen from the air to break down food molecules into smaller molecules called "...
Eventually these organelles leave the cell and a mature erythrocyte is formed. RBCs last an average of 120 days in the bloodstream. When RBCs age, they are removed by macrophages in the liver and spleen. A hormone called erythropoietin and low oxygen levels regulate the production of RBCs. ...
developing xylem, as revealed by microarray analysis. Many NAC domain protein-encoding genes are suggested to regulate wood formation in poplar, and these genes likely have conserved functions between poplar and Arabidopsis [82]. Additionally, microarray analysis identified genes involved in cell death,...
Though the team uses model systems to examine individual properties of thedroplets, it's likely that many forces work together in a cell to determine the behavior and function of the organelles, he says. There may be multiple other mechanisms, for example, that cause MLOs to take on a ge...
What structure (found in all cells) surrounds the cell membrane and gives support to the cell? Are there organelles found in epithelial cells? What is the function of the neuroglial cells? How do cells communicate with one another? Explain how the plasma membrane helps with this function. Wh...
A cell has 36 chromosomes. After it divides by mitosis, how many chromosomes will be in each cell?What is the number of chromosomes in a somatic cell? And how many chromosomes are there in a gamete (sex cell)?A parent cell containing 32 chromosomes will...
