Photosynthesis - Cellular Respiration

reactants ( photosynthesis )

a substance or molecule that participates n a chemical reaction ( ex: carbon dioxide - CO2 and water - H2O)

products ( photosynthesis )

a substance that forms in a chemical reaction ( ex: glucose )

ATP ( adenosine triphosphate )

energy storing molecule, fuels cell activities

chlorophyll

a green pigment found in plants that absorbs light energy for photosynthesis.

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

photosynthesis formula

carbon dioxide ( CO₂) and water (H₂O)

what are the reactants of photosynthesis

glucose (C₆H₁₂O₆) and oxygen (O₂).

what are the products in photosynthesis?

autotrophs ( one )

what organisms perform photosynthesis?

autotrophs

make their own food

plants, algae, some bacteria, and some protists

examples of autotrophs

sun

autotrophs harness energy directly from the..

heterotrophs

break down molecules

animals and other organisms

examples of heterotrophs

autotrophs

heterotrophs rely on eating __ for energy

leaf

mesophyll cells =

chloroplasts

organelle necessary for photosynthesis, contains chlorophyll

chlorophyll and other pigments

what do chloroplasts contain?

sunlight

what do chloroplasts absorb?

green

what do chloroplasts reflect?

thylakoid

photosynthetic membrane containing pigments ( chlorophyll )

granum

what is a stack of a thylakoid called

stroma

fluid surrounding thylakoids

sunlight

what do thylakoids absorb

phase 1- light dependent reactions, phase 2- Calvin cycle ( light independent )

what are the phases of photosynthesis?

thylakoid

the light depend reactions happens in the..

chloroplast

site of photosynthesis

cellular respiration

process occurs in mitochondria

Anaerobic

process that does NOT require oxygen

Aerobic

process that DOES require oxygen

energy

the ability to do work

ATP

energy storing molecule

Glycosis

The anaerobic process of spitting glucose and forming two molecules of pyruvic acid

Light dependent

the starts the process of photosynthesis

light independent

this process does not require sunlight

chlorophyll

the pigment that traps sunlight

thylakoidd

light dependent reactions takes place in the..

stroma

light independent (Calvin Cycle) takes place in the..

oxygen or 02

what is the byproduct of photosynthesis?

chloroplast

where does the byproduct of photosynthesis come from

energy, water

what are the starting molecules of the light dependent reactions

oxygen, ATP, and NADPH

what are the proucts of the light dependent reactions

C02, ATP, NADPH

what are the starting molecules for the Calvin Cycle?

glucose

what are the products for the Calvin Cycle?

mitochondria

in what cell organelle does cellular respiration occur if energy is used?

cytoplasm

in what cell organelle does cellular respiration occur if no energy is used?

glucose and oxygen

what are the two reactants needed for cellular respiration

Carbon dioxide, water, energy

what are three products of cellular respiration?

carbon dioxide and water

what is the byproduct of cellular respiration?

mitochondria

where does the byproduct of cellular respiration occur?

anaerobic

is glycolysis anaerobic or aerobic?

aerobic

is Krebs Cycle anaerobic or aerobic?

aerobic

is ETC(electron transport chain) anaerobic or aerobic?

cytoplasm

where does glyoclysis occur?

matrix of mitochondria

where does Krebs Cycle occur?

across cristae of mitochondria

where does ETC ( electron transport chain ) occur?

2

how much ATP does glycolysis make?

2

how much ATP does Krebs Cycle make?

32

how much ATP does ETC ( electron transport chain ) make?

36 ATP

what is the total amount of ATP made from one glucose

Glycolysis

process by which glucose is split into two molecules of pyruvate or pyruvic acid.

Krebs Cycle

process by which pyruvic acid is broken down. It is a cyclical series of oxidation reactions that give off CO2 and produce 1 ATP per cycle

ETC ( electron transport chain )

uses high energy electrons from the Krebs Cycle to convert ADP into ATP
