The (a) Vacuole is present in plant cells and fill with water, allowing cells to maintain size and turgidity without creating more cytoplasm
The (a) Vacuole pumps water out of the cell. This vacuole is extremely important to unicellular organisms.
The (a) Vacuole forms after Phagocytosis (the usage of the plasma membrane to absorb food) and contains the captured food.
There are three main components of the Cytoskeleton. Which one is described as hollow rods constructed from tubulin proteins, which are resistant to compression. In animal cells these grow out from a centrosome near the nuclease.
(a)
There are three main components of the Cytoskeleton. Which one is described as a thin solid rod built from globular actin subunit that is resistant to pulling motions. It is also useful in regards to muscle contraction.
(a)
Now we're moving on to Cellular Metabolism!!!! Yay!!

Anabolic Pathways break down molecules
True
False
Draw a graph that demonstrates a reaction with negative delta G (exergonic) !
Draw a graph that demonstrates a reaction with positive delta G (endergonic) !
Life prefers a higher G (free energy) and low G systems tend to be considered unstable
True
False
What is primarily used for energy coupling (the use of exergonic processes to drive an endergonic one)
(a)
Endergonic reactions are fueled by what?
(a)
ATP Hydrolysis changes the shape of a protein which allows for Mechanical and Transport Work
True
False

Oxygen is reduced and Glucose is oxidized
CO2 is reduced and Glucose is Oxidized
There are 4 stages in cellular respiration. Which one:
- Takes place in the cytoplasm
- Has an input of 2ATP, Glucose, and NAD+
- Has an Output of 4 ATP, Pyruvates, NADH
(a)
There are 4 stages in cellular respiration. Which one:
- Uses an electrochemical gradient to fuel ATP synthase
- Has NADH and FADH give their electrons to pump H+ outside the mitochondria
(a)
There are 4 stages in cellular respiration. Which one:
- Has inputs of 2 Acetyal COA, 6 NAD, 2 FAD, 2 ATP
- Has Outputs of 4 CO2, 6 NADH, 2 FADH, and 2 ATP(net)
- Using Substrate level phosphorylation
(a)
There are 4 stages in cellular respiration. Which one:
- Adds an H+ to NAD+ to become NADH
- Has coenzyme A added to create Acetyl CoA, which is highly reactive
(a)
Photosystem I requires the breakage of water in order to replace the electron lost
True
False
Is this description of light reaction correct? read carefully
Light is absorbed by the Photosystem II (680) exciting an electron. This electron then reaches the reaction center and is transferred through the cytochrome complex. Water is then split to replace the electron lost. As the electron moves some of the energy is used to pump protons (H+) from outside to inside. Then light is absorbed by photosystem I (700) and it takes the electron to an even higher energy state. It is then passed to NADP+ (oxidized) and turns into NADPH (reduced). As you pump protons you create a charge and using oxidative phosphorylation you can make some ATP.
Yes
No
