Exam 3 Flashcards
(41 cards)
What happens if cells run out of Oxygen, like during exercise?
Fixed by Mr. Birkmire
D3.2-5
They switch to fermentation to create ATP
Then they can not use the Electron Transport Chain to create massive amounts of ATP
How do plants use energy efficiently?
Fixed by Mr. B
D.3.1-7
Capture sunlight in light-dependent reactions when the sun shines; use stored energy in NADPH and ATP when it is dark
What is the rigid wall made up of cellulose that supports, protects, and holds the cells’ shape?
B3.2-3
Cell wall
(outer layer of a cell) It is different than a cell membrane.
What is the large storage tank that holds water and nutrients?
Central vacuole
Also controls cell’s turgitity (stiffness)
What are the bi-products of the light-dependent cycle?
O2 (oxygen) and ATP and NADPH
What do producers do?
A3.1-1
Producers harness energy from the sun to create energy-rich glucose (photosynthesis). They make their own “food” from the sun.
Plants and related organisms
When a plant is wilting it’s turgor pressure is…
high or low?
B3.1-3
Low!
Think of it like a balloon. If it has low pressure, it will be weak
What happens in the second step of cellular respiration?
Fixed by Mr. B
C 3.2 - 3
The Krebs cycle/Citric acid cycle
Pyruvate goes and gets broken down and recycled a bunch to create large amounts of NADH to go to electron transport chain
What are the two phases of photosynthesis, and where do they happen?
Light dependent (thylakoids) and light independent/dark phase/calvin cycle (stroma)
D-3.1-7
What are primary consumers?
(Herbivores) eat producers to survive.
What are the energy packets of sunlight called?
Fixed by Mr. B
Photons
F3.1-5
What does a decomposer do?
They recycle dead organic matter back into soil for plants to reuse.
How do plants continue to produce Glucose when there is less sunlight?
D3.1-7
Stored energy from previous reactions (from calvin cycle or light independent reactions) in the form of ATP and NADPH
See “Why did God make 2 different phases?”
What goes in the light-dependent cycle to create O2?
H2O; ADP/NADP+ go in to be recharged
What does ATP synthase do?
Fixed by Mr. B
It uses the passive diffusion of H+ from outside the mitochondria to convert ADP to ATP
What is a waste product in Alcoholic fermentation when breaking down pyruvate?
D.3.2-5
2 CO2
What is the location of photosynthesis?
B3.1-2
The Chloroplast
What is the first step of photosynthesis?
Chlorophyll gets hit with sunlight within the thylakoids, electrons get excited by moving to a higher energy orbital
What makes up sunlight?
Identitfy what makes up sunlight and describe what it does.
B3.1-3
Photons, they are used for Transmitting Energy: Photons transmit energy from one place to another and are responsible for the interactions of electromagnetic radiation with matter. For example, they carry energy from the Sun to Earth, allowing us to see and feel warmth.
What is Glycolysis?
B3.2-2
Glycolysis is the breakdown of glucose to create ATP. At the end of glycolysis, glucose is broken down into pyruvate, generating ATP molecules and NADH molecules.
What molecules plus sunlight and chlorophyll make 1 glucose?
Happens during photosynthesis.
E3.1-6
The molecules include CO2 and H20 as reactants
Alcoholic Fermentation is used in…
D3.2-5
Yeast and Bacteria
How does ATP release energy?
By the breaking of the Phosphate group
What organism eats other consumers transferring solar energy up the food chain?
A3. 1-1
Secondary/ Teritary Consumers
