Answer: produce energy; photosynthesize
Explanation:
Mitochondria and Chloroplast are similar because both are cellular organelles involved in ENERGY PRODUCTION:
- Chloroplasts in green plants, due to its membrane containing chlorophyll molecules produces energy during photosynthesis
- Mitochondria in animal cells produces energy in form of ATP during lipid oxidation occuring in its membrane.
However, both organelles DIFFER in that ONLY CHLOROPLAST allows photosynthesis in its membrane, unlike Mitochondria
If a researcher electrically stimulates the reticular formation in an animal, the animal will immediately wake up and be alert. Its purpose is to have some control of sensory signals and thus has the ability to alert the body when it is tired or needs to be awake.
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:
Which of the following statements about the cytoskeleton is false?
The cytoskeleton helps organize the cell’s structure and activities
Explanation:
Answer:
Phenylalanine.
Explanation:
The A site (aminoacyl) is the first binding site in the ribosome. In this case, in the exit site is GAC (Asparagine), next to it is CAU, for the Histidine referred in the question as reference, and then, in the A site you find UUU, that according to the genetic code translates in phenylalanine.
