Photosynthesis/Respiration Day 1Learning Target: Students understand how energy flows from the sun to plants and other living things

Agenda: 1) Missing Biome Projects2) Test Makeup assignment due.3) Respiration Lecture (short) + notes4) Reading assignment (finish in class

so you don’t have homework!)

So we have this chemical energy… now what?(glucose)

RESPIRATION – getting energy from food

RESPIRATION – getting energy from food

STEP 1:

RESPIRATION – getting energy from food

STEP 2: CO2

STEP 3:

RESPIRATION – getting energy from food

Respiration Notes 11. Both heterotrophs and autotrophs need to be able

to turn the sugar they make/eat into a form they can use.

2. This chemical process for this is called RESPIRATION. It occurs in the Mitochondria (organelle that provides power for the cell) and has the following chemical formula:• Glucose + Oxygen Carbon Dioxide + ATP +

Water3. Respiration has 3 major steps:

1. Glycolysis - each molecule of glucose is split into 2 pyruvate

2. Krebs Cycle – uses the pyruvate to make NADH, an electron carrier

3. Electron Transport Chain (or ETC) – uses the electron from NADH to make ATP, a form of chemical energy our body can use.

ETC – ELECTRON TRANSPORT

Respiration Notes 2

1. The electron from NADH is used to pump H+ ions into a space in the mitochondria.

2. When lots of H+ ions build up in that space, they want to leave and go to the inner part of the mitochondria.

3. Mitochondria use the energy from H+ ions moving to make ATP.

Reading Review of Respiration

Reading assignment (homework if not finished)

Read section 8.3 in the zebra book (main textbook)Do questions 28-41 on pages 238 – 239.

Photosynthesis/Respiration Day 2Learning Target: Students understand how energy flows from the sun to plants and other living things

Agenda: 1) POGIL self-guided learning

(practice, practice, practice)2) Make your lab reports beautiful so

that they come into my life like a wrecking ball LATE REPORTS WILL BE

DOCKED 20%

1. a: Glucose b: 6 carbons2. a: Pyruvic acid (similar to pyruvate) b: 3 carbons3. Glucose (6 carbon) is split into two 3 carbon pyruvates in glycolysis4. Similar to question 35. Two ATP molecules are used up to split glucose into pyruvate – however we

produce 4 during the process of glucose. 4 produced – 2 used = 2 total made. 6. NADH and FADH2 are produced during glycolysis.
