Organelles and their functions

The digestive organelle in cells requires a pump to moveH⁺ against its concentration gradient to maintain anacidic environment. Based on this information, determine whichgroup of terms can be used to explain this to a classmate.

(a) Mitochondria, uniport, active transport

(B)Lysosome, uniport, active transport

(C)Mitochondria, symport, passive transport

(D)Lysosome, symport, passive transport

(E)Mitochondria, channel protein, active transport

Mid-Unit Assessment, Part 2: Cell Biology Complete this teacher-scored portion of the assessment and submit it to your teacher.

Question 1:

1. Some cells produce and secrete high levels of digestive proteins.

Which organelles would you expect to be abundant in those cells, and why?

Answer:

Question 2:

2. Explain how active transport helps a nerve cell maintain its resting potential.

Answer:

Question 3:

3. The Atlantic cod is a common fish of the Atlantic Ocean that must drink seawater to meet its water needs. Explain how active transport helps the Atlantic cod maintain homeostasis with regard to the balance of sodium and chlorine ions, which are abundant in seawater.

DNA to Proteins

You are given the DNA template:

A-A-T-A-G-T-A-C-G-C-G-A-G-T-C-G-T-G-A-T-G-A-A-A-T-T-C-T

Complete the following exercise:

A. DNA replication. Write the sequence of complementary basesproduced if the above DNA template

undergoes replication. (Hint: The complement strand sequence isbased on complementary bases A

pairs with T, C pairs with G.)

B. Transcription. Using the original DNAtemplate, construct the sequence of nucleotide bases for the

transcribed RNA strand. (Hint: similar to question A, except,Uracil instead of Thymine.)

C. Translation. Using the RNA strand produced in part B as yourmRNA molecule. Translate the codons in

the mRNA into amino acid sequence of a protein. (Hint: lookingfor start codon for the first amino acid

and the translation stops at the stop codon.)
