Answer:
A
Explanation:
Golgi apparatus is an organelle in eukaryotic cells that stores and modifies (might include addition of sugar groups) proteins and lipids for certain functions and prepare them for transport to other parts of the cell.
In the Endoplasmic reticulum, proteins fold into into their correct shape. Some of them are transported to the Golgi apparatus in membrane vesicles. Some proteins need to do their jobs in the Golgi (they are said to be Golgi-resident). They are transported from the golgi appratus to their final destinations through a secretory pathway. It involves sorting proteins into different kinds of transport vesicles, which emanate from the trans Golgi network and deliver their contents to the appropriate cellular locations.
Proteins that are membrane embedded are conveyed to the plasma membrane (integral membrane proteins) by constitutive secretion. Proteins can divert from constitutive secretion pathway and be targeted towards other destinations such as lysosomes (as lysosomal proteins) and regulated secretion from cells (to the cell exterior).
Answer:
Earth's primordial soup
Explanation:
Alexander Oparin was a Soviet biochemist who proposed theories for the origin of life through a book he called "The Origin of Life". He claimed that life on earth came about as a result of a gradual chemical evolution which is a mixture of carbon-based molecules that he called Earth's primordial soup (or sometimes called "organic soup").
I believe your answer is C)High temperature due to other layers keeps the particles close together.
sorry if im wrong
Answer:
Most likely it should be Mitochondria.
Explanation:
Centrifugation of cells :
At first, large components undergo precipitation such as whole-cell nuclei, cytoskeleton. They form a pellet at the bottom of the centrifuge tube at a low speed. Then at medium speed mitochondria, lysosome, peroxisomes form the pellet and after that at higher speed microsomes, small vesicles form a pellet. At last at very high speed, ribosomes, viruses, and macromolecules form their pellet.
- Mitochondria will be the most suitable option because mitochondria are the only substance that can produce ATP.
Characteristics of Endocytosis:
* use energy
* takes substances into a cell
* moves substances in vesicles
Characteristics of Exocytosis:
*use energy
*releases substances outside a cell
*moves substances in vesicles.
Both use energy and move substances in vesicles.
