Biology Chapter 6

Front

What is ADP?

Back

ADP (Adenosine Diphosphate) is a molecule that consists of one phosphate group and is involved in energy transfer within cells.

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) picks up amino acids in the cytoplasm and aligns them with codons on the mRNA strand to build protein chains.

Front

What is translation in biology?

Back

Translation is the process where the transcribed strand of RNA is read by cellular machines to assemble amino acids into proteins.

Front

What is a ribosome?

Back

A ribosome is a cellular structure that contains three active sites; two hold tRNAs and one is the exit site for tRNAs that have released their amino acids.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that obtain their energy by consuming other living things.

Front

What is the role of ATP in cells?

Back

ATP (Adenosine Triphosphate) serves as the primary energy carrier in cells, providing energy for various cellular processes.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own energy through photosynthesis or chemosynthesis, while heterotrophs obtain energy by consuming other organisms.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, which then carries the genetic information to the ribosome.

Front

What are codons?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids during protein synthesis.

Front

What is a peptide bond?

Back

A peptide bond is a chemical bond that links amino acids together in a protein chain.
