CP1 Biology Assignments

ch 22 test sample attached

Exam Test Chapters:

6,7,8,10,17,18,20,21,22

 

We will pass out old tests and answer sheets this week as your study guide. The exam will be mostly composed of old test questions from the 2nd semester tests. The exam will have 200 questions.

Plant Leaf Project

 

 

Each group of 2 students will be responsible for “10” different specimen.

 

• 1 fern

• 1 grass

• 1 clover

• 2 oak trees

• 1 rhododendron

• 1 pine tree

• 1 moss

• 1 vine

• 1 citrus

 

 

Each leaf specimen will be mounted on card stock paper. You can do up to 2 leaves per page. Color of the paper can be of the collectors choosing. Each specimen should include a typed form explaining the following:

 

• Family , Genus , species Name

• Date collected

• Location gathered

• Conditions of habitat

• Resource for plant identification

• Collectors Name

• Class period

 

Projects will be due by Tuesday, May 17th

Each specimen will be worth 10pts for a total of 100pts.

 

 

 

The chapter 21 Test will be moved to Thursday due to the underclassmen awards. This will give students a chance to correct their study guides.    There is extra material on the study guide from ch 22 that will not be on the Test.

For the study guide, you may omit questions #36-47 in the modified true false and #39-48 in the completion section. The information for those questions is found in ch 22.  Thursdays test will only cover ch. 21 material.

here are the chapter 21 notes

Cellular respiration study guide:

 

“ the processes that convert the stored chemical energy in macromolecules to ATP”

 

Glycolysis : “sugar breaking”

occurs in the cytoplasm and does not require oxygen ( anaerobic)

 

Glucose is broken down ( basically in half) using 2 ATP molecules to gain 4 ATP molecules

a net gain of only 2ATP

2% efficient ( most of the energy is the glucose is untapped)

 

final products of glycolysis :

Net 2 ATP, 2 molecules of NAD are reduced to 2 NADH, 2 waters , 2 pyruvic acid molecules( 3-carbon molecules)

 

Intermediate steps:

after glycolysis, pyruvic acid will travel to the matrix on the mitochondria ( the middle)

on its journey there, it will be oxidized again yeilding 1 carbon dioxide molecule

the resulting 2-carbon molecule is bonded to Coenzyme -A to now be called Acetyl Co-A

Acetyl-Co-A is the entry molecule to the Krebs Cycle ( citric acid acycle)

 

 

Kreb's Cycle ( citric acid cycle)

 

The kreb's cycle is a series of enzyme catalyzed steps inside the mitochondrial matrix where a 6-caron molecule of citric acid is oxidized to create several proton carrying co-enzymes ( NADH and FADH2).

 

These co-enzymes will eventually donate their protons for the creation of a proton gradient later in the electron transport chain across the cristae ( membrane projections of the inner membrane) of the mitochondria

 

Starting with the 6-carbon molecule, enzymes will slowly hack away at the large energy rich molecule, breaking off protons, electrons, and Carbon in the form of CO2.

 

During one turn of the kreb's cycle, the following are generated

1 ATP, 3 NADH, 1 FADH2, 2 CO2

 

( keep in mind , one turn of the krebs cycle only accounts for one pyruvic acid , glycolysis creates 2 per glucose)

 

After Ctitric acid is oxidized down to a 4-carbon molecule called oxaloacetic acid, the Acetyl Co-A will enter the cycle and add to the 4 carbon molecule , turning it into a 6-cabon molecule of citric acid, renewing the cycle. 4C ( oxaloacetic acid) + 2C( acetyl Co-A) = 6C ( citric acid)

 

Electroin transport chain

 

Electrons are pulled off of the NADH molecules and transferred along a serioes of membrane structures on the cristae ( inner mitochondrial membrane) until the electrons are ultimately added to the oxygen gas that is present.

 

Oxygen pulls the electrons through the chain and will eventualy be reduced to water as it gains electrons and protons.

 

Electrons passing through chain will turn on pumps along the way that will use active transport to pump protons from the matrix into the inner membranous space – creating a proton gradient in the inner membranous space

 

 

Chemiosmosis

 

Once a critical mass is reached, the protons will diffuse through an enzyme called ATP synthase on the membrane back into the matrix.

 

ATP synthase will utilyze the free energy of chemiosmotic diffusiuon to perfom oxidative phosphorylation

 

oxidative phosphorylation :the production of ATP using energy derived from the redox reaction of an electron transport chain

 

the final net production of ATP is 36 ATP per glucose when oxygen is present

Study guide 4-2

 

Section 4-3 Study Guide

 

* photosynthesis – the creation of high energy carbon molecules from sunlight, carbon dioxide and water

 

*. light reaction take place on the thylakoid membrane

*. photosystem 2 come before photosystem 1

*. light reactions require – water, sunlight

*. heres what happens

1. photosystem 2 absorbs unlight using chlorophyll

2. water is split by the water splitting enzyme- yielding electrons, protons, and oxygen gas

3. oxygen gas is a waste product, electrons are now transferred to the electron transport chain

4. protons will be pumped into the thylakoid by membrane pumped turned on by the electrons

5. electrons lose energy as they travel down the chain, but a proton gradient is created in the thylakoid

6. electrons are reenergized as they enter photosystem 1.

7. these newly excited electrons are used to reduce NADP to NADPH

8. ATPsynthase is a ion channel/enzyme that captures the free energy of diffusion when the proton gradient is diffused through its opened channel. This channel opens once the proton gradient reaches critical mass. Diffusion occurs in the directionon the stroma.

9. the final products of the light reactions are ATP and NADPH as well as a waste product of oxygen gas.

 

* the light independent reactions:

1. require the products from the light-dependent reactions ( NADPH and ATP) and carbon dioxide gas

2. uses a 3 carbon molecule as a platform to capture Carbon from carbon dioxide gas

3. high energy 3-carbon molecules are released from this recycled molecule .

4. 2 high energy 3-crabon molecules can be combind to form glucose

5. the original 3-carbon molecule is recycled in a process called the Calvin Cycle.

6. the Calvin cycle occurs in the stroma.

7. The calvin cycle can occur both during the night and the day.

 

Be able to label the chloroplast!
