3. A strain of cells undergoes a mutation that increases the permeability of the inner
mitochondrial membrane to hydrogen ions.
a) What effect would you expect this mutation to have on the process of cellular
respiration? 12
b) Assuming the mutant cells can survive, how might the metabolic requirements of
these cells differ from those of a non-mutant strain of the same variety? 12

Answers

A mutation that involves the permeability of the inner mitochondrial membrane to protons (H+) will affect the amount of ATP. If mutant cells can survive, then they will need more energy to create a suitable gradient.

Cellular respiration is a series of metabolic reactions by which aerobic cells can generate energy in the form of ATP by using the chemical energy stored in the foods.

Cellular respiration can be divided into three sequential stages: glycolysis, the Krebs cycle (also called the acid citric cycle) and oxidative phosphorylation.

During oxidative phosphorylation, the transport of electrons across the inner mitochondrial membrane is coupled to the generation of an electrochemical proton (H+) gradient, which is then used to generate ATP by means of a protein complex known as ATP synthase.

Why can cells in the bone marrow produce both red and white cells

Answers

Answer:

1.Bone marrow produces red blood cells, platelets, and white blood cells. Lymphocytes are produced in the marrow, and play an important part in the body's immune system.

Explanation:

2.After entering the bloodstream, the hematopoietic stem cells travel to the bone marrow. There, they begin to produce new white blood cells, red blood cells, and platelets in a process known as engraftment.

3.Red blood cells are an important element of blood. Their job is to transport oxygen to the body's tissues in exchange for carbon dioxide, which they carry to the lungs to be expelled. Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts.

Cell Division Virtual Lab Activity

Instructions: The Virtual Cell Division Lab is on the lesson assessment page. On the image, it says “Click Anywhere to Start.” Follow the instructions as you move through the lab. The lab activity will keep count of your data on the right, and you can record this into the data table.

Title: Cell cycle

Objective(s):

Hypothesis:

Variables:


Data:
Record the number of cells you observed in the lab activity.

Stages
Number of Cells
Interphase


Prophase


Metaphase


Anaphase


Telophase


Cytokinesis




Observations:
Record any observations about the cells you observed. What does the cell look like for each stage? What is a distinguishing visible feature of each stage of the cell cycle?
Stages
Description of Cell
Interphase


Prophase


Metaphase


Anaphase


Telophase


Cytokinesis



Data Analysis:
Part 1: Calculate the percentage of the cell cycle spent in each stage. Number of cells in given stage ÷ total number of cells counted × 100 = % of the cell cycle spent in this stage

Part 2: Using your percentages in part 1, create a graph that represents the time spent in each stage of the cell cycle.

Insert Chart [Hint: don’t forget to consider the relationship between your data and the type of chart to best represent your data]

Conclusion:
Be sure to answer the following reflection questions as a summary in the conclusion of your lab report:
Was your hypothesis correct? Why or why not? Be sure to include evidence from the data you collected to support your conclusion.
Based on your data, what can you infer about the length of time spent in each stage of the cell cycle?
What stages were the longest and shortest? Give a brief explanation of why these stages may have that time period.

Questions:
Using what you have learned in the lesson and the virtual lab activity, answer the following questions in complete sentences.
What differences can you see when you compare the nucleus of a dividing cell with that of a non-dividing cell?
If your observation had not been restricted to the tip of the onion root, how would the results be different?

Answers

The distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.

What is the cell cycle?

The cell cycle is a series of well-defined steps in the life of a cell that begins with cell growth and end with its division.

The cell division has a series of steps that may be classified according to the phenomena that occur in these phases.

For example, chromosomes condense during the first stage of cell division (prophase), where they migrate to the equatorial plate at metaphase.

In conclusion, the distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.

Match the digestive organ on the left with its function.

Answers

Answer:

pancreas: secretes digestive enzymes into the small intestine

esophagus: the place where peristalsis takes place

small intestine: area of the digestive tract where most nuturients are absorbed

stomach: area of the digestive tract that follows the esophagus

large intestine: area of the digestive tract where mostly water is absorbed

Explanation:

peristalsis: so the food can move down towards your stomach, independently of gravity

pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes

small intestine: it is really really long -> more time to absorb nutrients

large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place

Answers

The amino acid sequence here is Met-Ser-Asp-Trp.  The start codon is AUG, while the three stop codons are UAG, UAA, and UGA.

The triplets of nucleotides or codons in mRNA determine the order of amino acids that will be added to the protein during translation.

The start codon in the genetic code is AUG and it encodes for the amino acid methionine (Met).

The 3 stop codons in the genetic code are UAG, UAA, and UGA. These codons do not code for an amino acid.
