Answer:
After a cell was treated with a certain chemical, the ribosomes stopped functioning. The cell activity immediately affected by this change in ribosome function is protein synthesis.
Explanation:
The basic structural units of all living things are known as cells. Inside the cells, specialized structures called ribosomes are present, which synthesize proteins. The protein synthesis in a eukaryotic cell consists of two processes, transcription and translation.
The transcription process takes place in nucleus, where the information from a DNA strand is copied into a single stranded messenger RNA (mRNA) molecule using RNA polymerase enzyme. During the ending of transcription, the completed mRNA strand detaches from DNA and exits the nucleus and goes into a ribosome in the cytoplasm. In the ribosome, translation occurs where the genetic code in mRNA is read and protein is synthesized. These proteins are used by cells to perform important functions such as repairing cellular damage, maintain cellular structure, create hormones, cell division etc.

DNA ligase is like the glue that pieces together DNA. DNA polymerase "unzips" the DNA helix in DNA replication.
Answer:
There are two types of vesicle transport, endocytosis and exocytosis (illustrated in the Figure below). Both processes are active transport processes, requiring energy. Illustration of the two types of vesicle transport, exocytosis and endocytosis.
Explanation:
So in a simple explanation yes they require energy:)
Answer:
a. Mastication process and formation of bolus in the oral cavity
b. The contraction in the stomach breaks the food down into smaller pieces. These pieces are then moved to the small intestine.
c. In the small intestine, food particles are broken down into nutrients, fat, protein and carbohydrates which are absorbed into the bloodstream.
Explanation:
a. First step of digestive system functioning is the mastication process and formation of bolus in the oral cavity.
b. The contraction in stomach, with the help of digestive enzymes and acids, break the food down into smaller pieces. The small pieces of food are then released into the first part of the small intestine (duodenum).
c. In the small intestine, two enzymes released from pancreas and gall bladder break down the food particles into fats, proteins, and carbohydrates. Thereon, nutrients and carbohydrates, proteins and fats are absorbed into the bloodstream.
