Season's Greetings

Have a happy holiday and all the best for the new decade.

See you next year.

Multiple Choice Test on Photosynthesis

Photosynthesis vs Cellular Respiration

You will work in groups of two using pictures and words to compare and contrast photosynthesis and cellular respiration. 
You will not use your notes or the textbook for this assignment.

Permeability Lab

To determine the permeability of the membrane of the dialysis tubing.

Questions and Answers

You will answer question related to the chapter.  This will help you to prepare for the test on Tuesday.

Diffusion

You will be taught about the movement of molecules.
The topic will be centered around tonicity- hypertonic, hypotonic, and isotonic solutions.

(Additional notes on the current chapter can be found in Google Classroom.  Information on The Plasma Membrane is listed on pages 6-9 on the link posted in  "A View of the Cell".
Information on diffusion and osmosis can also be found in Google Classroom.)


 The relative concentration of solutes dissolved in an aqueous solution which determines the extent and direction of flow of water.

The Plasma Membrane

You will take notes from the PowerPoint.



 

Enzymes

A More detailed  look at Enzymes

Class Activity

You will work individually to summarize the differences between words or phrases studied so far in this chapter. 
In addition, you will demonstrate your understanding of how enzymes work.

Endergonic and Exogonic Reactions

Photosynthesis is an example of an endergonic reaction:









 Exergonic Reaction:

The Working Cell- Enzymes

Introduction to The working cell.  You will take notes from the PowerPoint.

 The enormous of biochemical reactions occurring within cells is regulated by enzymes.  Enzymes speed up chemical reactions, as well as control the rate at which reactions occur.  They are globular protein molecules manufactured by each cell.  More than 2000 enzymes have been recognized based on the chemical reactions they catalyze.  All of them are structurally different.



An enzyme recognizes a specific molecule called a substrate and binds to it.  Some enzymes are so specific they only act on one substrate, while others can act on a class of substrate.

Enzymes can bring about changes to molecule to which it binds. The change usually involves the forming or breaking of a covalent chemical bond.  Enzymes may split the substrate into two pieces, may add a chemical side group to the molecule, or may simply rearrange the bonds in the substrate.

 Enzymes lower the activation energy by 1) providing a medium that is more favorable than the surrounding one. 2) By bringing the reactant into close contact. 3) They might add or remove a proton from the substrate , strain the substrate molecule's bond, or even form temporary covalent bond between the substrate and some part of the enzyme itself.

Question and Answers

Happy Halloween

                                                                                            


We will grade the review questions from yesterday.  The questions came from pages 192 - 193 from the textbook.  Copy of which is posted in Google Classroom.  Questions numbers 1 -17 and 19 - 23.

Organelle test on Friday, November 1, 2019

Notes form the PowerPoint

Multiple Choice test on Friday.

Cell Analogy Project

Today is the final day to work on the project.

Cell Analogy Project

You will work to compare the organelles of the animal cell to the parts of a factory, city, country, movie or any other organization of choice.  
You will work in groups of 2.

You must draw the items that you are comparing the organelle to. In addition, list the function of the organelle and explain why you think the comparison is similar to the organelle.

The organelles to be included are:
1) The mitochondrion
2) Golgi apparatus
3) Nucelus
4) Ribosomes
5) Rough Endoplasmic reticulum
6) Smooth Endoplasmic reticulum
7) Plasma membrane
8) Cytoplasm
9) Lysosome
10) Vesicle
11) Perosisome
12) Cytoskeleton
13) Nucleolus.

Points will be awarded for the presentation ( appearance). 

Functions of the Organelles

 The drawing of the animal cell is due on Friday, October 25, 2019
We will discuss the organelles present in the plant cell but  not the animal cell and vice versa.

The Functions of the Organelles

You will take notes on The Functions of the Organelles.

Cell Types

A Bacterial Cell

 

 

The Animal Cell

 

 

Introduction to the Microscope.

1) You will learn the parts of the compound light microscope and their functions.
2) You will learn how to calculate the magnification of the light microscope.
3) Learn how to make a wet mount slide
4) Understand how movement of the image changes as viewed through the microscope.
5) Learn the proper use of the low and high power objective lenses.
6) Learn the proper use of the coarse and fine adjustments for focusing.  
 

A Tour of the Cell

The microscope played a significant role in realization that living things were made up of cells. This realization lead to the Cell Theory:
1) All living things are made of one or more cells,
2) Cells come from pre-existing cells,
3) Nothing less than a cell can show the properties of life.

You will work with two food items to observe the positive test for glucose and starch.

Macromolecules Continued, Proteins and Nucleic Acids

It is only in the nature of the varian (R) that amino acids differ from another.  There are only about twenty differetn amino acids that occur in the protein of living organisms, although there are about 2000 natural and artifically made amono acids.

There are ten amino acids that cannot be synthesized by the body and must be obtained in the diet.


Nucleic Acids:
If proteins are the building blocks of life, then nucleic acids are the blue print.The DNA has the instructions and directs the RNA in the functioning of the cells and the synthesis of proteins.
