What is the relationship between photosynthesis and glucose

Photosynthesis makes glucose

What is the relationship between Cellular Respiration and Glucose

Cellular Respiration breaks glucose

What are the 3 Stages Of Cellular Respiration?

1. Glycolysis

2. Krebs Cycle

3. Electron Transport Chain

Where is the Glycolysis found in?

Cytoplasm

What is the role of Glycolysis

Breaks down glucose into two three pyruvate molecules, making ATP and NADH; makes 2 ATP

Where is the Krebs Cycle and ETC found in?

Mitochondria

What does the Krebs Cycle make

makes 2 ATP, NADH, and FADH2

What does C.H.O.N.P stand for?

Carbon, hydrogen, oxygen, nitrogren, phosphorous

Aerobic

with oxygen

Anaerobic

without oxygen

Chlorophyll

Pigment in plants that captures sunlight; reflects green

Where does photosynthesis occur?

Chloroplast

light independent reactions of photosynthesis occurs where?

In the thylakoid

what happens during the light-dependent reactions?

Light energy converts to Chemical energy. Chlorophyll absorbs light, splitting water to release oxygen, then uses electrons to create ATP + NADPH

Stroma

the fluid in chloroplasts, Calvin Cycle (light dependent reactions) occurs in here

What are the 2 stages of photosynthesis

1. Light dependent reactions

2. Dark dependent reactions

purpose of Dark Dependent Reaction

converts ATP + NADPH into glucose

ATP (photosynthesis)

Energy molecule made in light reactions

NADPH

carrier of high energy electrons made in light reactions; helps turn co2 into glucose

Organisms that undergo photosynthesis

Plants, algae, some bacteria

Electron Transport Chain

makes ATP: transports electron; makes approximately 34 ATP

lactic acid fermentation

anaerobic;sugars convert into lactic acid

Alcohol fermentation

yeast and bacteria converts sugar into alcohol and carbon

What does ATP stand for?

Adenosine Triphosphate

What is the relationship between Cellular Respiration and ATP

Cellular respiration produces ATP (from glucose)

NADH

electron carrier; carries HIGH energy electrons to E.T.C

FADH

electron carrier; carries LOW energy electrons to E.T.C

What organisms undergo Cellular respiration?

Plants, animals, fungi, most bacteria, protists

Amino Acids

molecules that are the building blocks of protein
