Quiz questions from weekly quiz (8 cards)
In the digestive system, glucose moves across the cell membrane against its concentration gradient. The movement of glucose is coupled to the movement of sodium. Sodium moves down a concentration gradient established by the sodium potassium pump. Glucose, in this case, is moving by ___________________.
Secondary Active TRasnport!
What is Secondary Active Transport?
Protein is synthesized from messenger RNA via the process of ________________ at the ribosome.
Translation
Messenger RNA is made from DNA through the process of _______________
Transcription
The tendency for randomly moving ions to move down a concentration gradient drives the process of _______________.
Diffusion
What is the movement of molecules and/or ions from areas of high concetration to areas of low concentration called?
Diffusion
What is Diffusion?
What is transcription?
Transcription is the process by which a specific segment of DNA—usually a gene—is copied into messenger RNA (mRNA). This mRNA will later be used during translation to build a protein.
The transcribed RNA sequence is read in sets of three nucleotides, called codons, with each codon corresponding to a specific amino acid.
