1What organelle is largely responsible for cellular respiration?
The mitochondria
2Are mitochondria present in plant cells?
Yes
3Anaerobic means
A process happens without using oxygen.

Membrane bound sac that contain chlorophyll
5Where do dark reactions (Calvin Cycle) occur?
The stroma
6Where are the most photosynthetic cells of the leaf located
In the Palisade Parenchyma
7Organisms that live in generally unlivable environments are generally
Called extremophiles and are chemosynthesizers
8What is the cuticle of a leaf?
Waxy substance that covers the epidermis of a leaf
9What types of organisms are considered autotrophs / producers?
Organisms that produce chemical energy for themselves and others
10What molecules do all cells directly use for energy?
Adenosine Triphosphate (ATP)
11The food chain always “ends” with the same types of organismswhat are they?
decomposers
12Grasshoppers eat grass birds eat grasshoppers, what level of the food chain would a bird be?
Secondary consumer
13Photosynthesis and chemosynthesis are the two ways that ______________ make their energy?
Autotrophs
14What is made during the dark reactions (Calvin cycle)?
Glucose
15What are chlorplasts?
Organelles found in plants where photosynthesis occurs
16What is the purpose of the cuticle and the guard cell/stomata?
Regulates gas entering and leaving the leaf
17What is the main purpose of the xylem
Transports water from the roots to the leaves
18What is the main purpose of the Phloem
Transports glucose from the leaves to the rest of the plant.
19Where do light reactions occur?
The thylakoid
20What happens during photolysis
Water is broken apart into O2 and Hydrogen ions.
21What is made during the light reaction?
O2, ATP, and NADPH
22What is used to “drive the flow of electrons” in Photosynthesis?
Light Energy/ Sunlight
23During glycolysis glucose is broken down to create what?
2 pyruvate molecules
24What part of cellular respiration produces CO2?
The Krebs cycle
25Where does the Krebs cycle take place?
The mitochondria
26Where does glycolysis take place?
The cytoplasm (outside of mitochondria)
27Oxygen is not used during this stage in cellular respiration?
In Glycolysis
28Photosynthesis, temperature regulation, and gas exchange are th,
Major purposes of leaves
29About how much ATP is made during cellular respiration?
34-38 ATP molecules
30Glycolysis, Krevs cycle, and the electron transport chain are all part of
Cellular respiration
31What are NADPH, NADH, and FADh2?
Intermediate high energy molecules
32How many types of DNA does a plant have?
3: DNA in the nucleus, chloroplast, and mitochondria
33How is gas exchanged and regulated in plants; and what gasses are regulated?
Stomata - oxygen, carbon dioxide, and water.
34What is the benefit of having more than one metabolic pathway?
Different ways to produce ATP
35Why is oxygen so important in cellular respiration? What specifically does it do?
It is the final acceptor in the electron transport chain, meaning that the presence of oxygen allows ATP and water to be made during The ETC
