The organelle labelled mitochondria is involved in an important cell process. Identify the process that takes place in this organelle’s inner matrix.

Which eukaryotic organelle is covered by a single membrane, contains an acidic interior, and is important for intracellular digestion of proteins being brought into the cell by endosomes? the lysosome the mitochondrion the ribosome the peroxisome the nucleus

The endoplasmic reticulum (ER) and Golgi apparatus are two organelles that are not physically joined, yet materials can still be exchanged between them. How can materials, such as proteins, move between the ER and Golgi when these organelles are not touching each other? A) When a substance such as a protein needs to move between these organelles, it is first dismantled in one organelle, then reassembled when it arrives at the other organelle. B) Substances such as proteins can travel between these organelles within transport vesicles. C) None of these; a single molecule will not go from one organelle to another. D) Substances like proteins will move between these organelles by diffusion through the cytoplasm. ..

For smooth ER which macromolecule(s) ( carbohydrate, proteins, lipids, and Nucleic acids) contribute to the structure and function of this organelle. How does it contribute to the organelle function
