Concept explainers
To describe: The outcome of the electron transport chain (ETC) in both chloroplasts and mitochondria.
Concept introduction: Mitochondria are found in both plant and animal cells and are the sites of oxidative phosphorylation. Chloroplasts are found in autotrophic organisms and are the sites of light-dependent and light-independent organisms. Chloroplasts and mitochondria have DNA present in them to synthesize a few proteins involved in few reactions inside them. An electron transport chain is found in the inner mitochondrial membrane in eukaryotes, where it acts as a site for oxidative phosphorylation, a process through which ATP is produced through the use of ATP synthase. The electron transport chain is also found in the thylakoid membrane of chloroplast in photosynthetic bacteria.
To explain: The contribution of the proton gradient for ATP production in both chloroplasts and mitochondria.

Transcription and Translation Practice: (Video 10-1 and 10-2) A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense DNA strand and label the 5' and 3' ends. B. Use the antisense strand that you create in part A as a template to create the mRNA transcript of the gene and label the 5' and 3' ends. C. Translate the mRNA you produced in part B into the polypeptide sequence making sure to follow all the rules of translation. 5'-AGCATGACTAATAGTTGTTGAGCTGTC-3' (sense strand) 4arrow_forwardWhat is the structure and function of Eukaryotic cells, including their organelles?

Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas.
