proteins
Question 23

new organelles are made.
chemical energy is stored in the form of ATP.
genetic information is used to make proteins.

sunlight energy is converted into chemical energy.
Question 24
What is the difference between "free" and "attached" ribosomes?
(More than one correct answer possible)
Attached ribosome are attached to mRNA and are actively engaged in protein synthesis, while free ribosomes are in between translation cycles.
Free ribosomes produce proteins that are exported from the cell, whereas attached ribosomes make proteins for mitochondria and chloroplasts.
Free ribosomes are in the cytoplasm, whereas attached ribosomes are anchored to the endoplasmic reticulum.
Free ribosomes produce proteins in the cytosol, whereas attached ribosomes produce proteins that are inserted into the ER.
