Photosynthesis
the process in which autotrophs use the energy of sunlight to produce high-energy carbohydrates (sugars/starches) that can be used as food; to make with light
9
New cards
Photo
light
10
New cards
Synthesis
to make
11
New cards
Cellular respiration
a series of chemical reactions that break down glucose to produce ATP
12
New cards
Adenosine triphosphate
important cell compounds that cells use to store/release energy
13
New cards
Adenosine diphosphate
the precursor to ATP; needed to make ATP
14
New cards
Thylakoid
membranes of the chloroplast
15
New cards
Glycolysis
the process that breaks down glucose in the cytoplasm
16
New cards
Fermentation
the process in which the cell releases energy from food without the pressure of oxygen

sweet
18
New cards
Lysis
to rupture
19
New cards
Autotrophs
Organisms that make their own food
20

Organisms that obtain food by consuming other living things
21
New cards
Chlorophyll
The plants principal pigment
22

Others
25
New cards
Troph
To feed
26
New cards
Where does photosynthesis take place?
Inside organelles called Chloroplasts
27
New cards
How does color work?
It reflects light wave length
28
New cards
What are the stages of photosynthesis?
Light independent reactions and light independent reactions
29
New cards
Equation of Photosynthesis
6 CO2 + 6 H2O \= C6H12O6+ 6 O2
30
New cards
Difference between light-independant and light-dependant reaction?
Light dependant reactions require light
31
New cards
What are the stages of cellular respiration?
Glycolysis (Cytoplasm) → Krebs Cycle (Mitochondria) → Electron Transport cycle (Mitochondria)
32
New cards
Where do we get glucose?
Cellular Respiration: Food; Photosynthesis: creates it
33
New cards
What are the products produced after glycolysis?
4 ATP molecules, 2 pyruvic Acids
34
New cards
How many ATP molecules are needed to start the glycolysis process?
2 molecules
35
New cards
What are the products after the Krebs cycle?
NADH and FADH2
36
New cards
How many molecules of ATP does the breaking down of Glucose produce?
30-38 molcules
37
New cards
Light-dependent reactions
Uses energy from sunlight to produce adenosine triphosphate molecules; takes place in the Thylakoid membranes
38
New cards
Light-independent reactions
ATP and NADPH molecules produced in the light-dependent reactions are used to produce high-energy sugars from carbon dioxide
39
New cards
What makes up ATP?
5 carbon sugar group (ribose), and three phosphate groups
