Name all of the parts of a basic glycolipid

Sphingosine, long fatty acid chain, polar headgroup (sugar)

100

Name 3 pieces of evidence for why we believe the endosymbiotic theory for mitochondria.

Mitochondrial Genome, Circular DNA, RNA, Ribosomes, Splitting by Fission, Double Membrane

100
  1. What is the name of this (Red Box)


Granum/Grana



100

(T/F) Intermediate Fillamets grow at the plus end

False. Intermediate fillaments are not polar.

100

Adheren junction versus a desmosome. 

From the worksheet



200

How would we make a membrane more gel-like? Consider only saturation state.

Make the fatty acid tails more saturated/Add H+/Get rid of double bonds

200

What is the location of the Electron Transport Chain

CRISTAE of the Mitochondria


200

Water is split at (PS1/PS2)

PSII

200

What is the “dynamic instability” of microtubules?

Rapid growing and shrinking of MT’s by GTP hydrolysis rates. Over stabalizing or understabalizing are both bad.

200

What are the name of the gap junctions in plants?

plasmodesmata


300

Membranes are described as fluid mosaic. What example did we learn in class that prevents transporters and signaling molecules in the membrane from going totally will-nilly through the membrane?

Spectrin



300

FADH2 is (oxidized/reduced), and at which Complex (1/2/3/4/5/6) , its redox potential is (lower/higher) than NADH

Oxidized; Complex 2; Lower

300

When the special pair hands off its electrons it is (oxidized/reduced) and the mobile electron carrier is (oxidized/reduced)

Oxidized; reduced

300

You have a structure with 6 connected microtubules, 2 doublets, and 2 singlets, how many protofilaments do you have?

63 + 46 + 13 + 13 = 135

300

Plant cells can stretch because their microfibrils are (parallel, perpendicular, beside, underneath) the direction of elongation.

Perpendicular to

400

How many times does this membrane protein pass through the membrane?


8

This image shows pyruvate being turned into Acetyl-CoA. Give the names of the processes happening in the red boxes (must give scientific terms):


Decarboxylation of Pyruvate/ Reduction of NAD+

400

Explain photorespiration

Rubisco binds oxygen instead of CO2, creating only 1 3 carbon molecule, and one 2 carbon molecule
400

What is the nucleator of MTs. What special tubulin attached to this nucleator

gamma y-TuRC. gamma tubulins, followed by alpha then beta repeating

400

What happens if you have too much collagen in your skin



Your skin would be ultra stretchy/strong

500

Explain the Post and Jolly experiment and its findings. 

Should list:

- 3 to 2 pump ratio of Na+ to K+

- Na+ is pumped out against the gradient. K+ is pumped in against the gradient.

500

List the outputs (include amounts) of the TCA Cycle if we input 4 acetyl CoA

12 NADH, 4 FADH2, 8 CO2, 4GTP

500

In the first step of the calvin cycle ___ is added to ___ using ____ to get ____ which is later split into 2 ______


CO2; Ribulose 1,5 Bisphosphate(RuBP), Rubisco, 6 carbon intermediate, 2 3 carbon molecules (3 phosphoglycerate)

500

If cofilin isn't present in a cell what would happen.

f-actin would grow out of control and not be depolymerized efficiently


500

A neutrophil is on its way to a chemoattrant. Describe the movement of the neutrophil

actin polymeryzation at the front end, myosin motors at the back end
