CAM photosynthesis

(the night part gives it away)

True or False. Typically the two daughter cells produced by mitosis are genetically the same.

True

Match the following stages of aerobic cellular respiration to where it takes place within the cell. (glycolysis)

cytosol (cytoplasm)

The diagram above shows a pathway where the end product of shuts down the pathway by binding to the allosteric ("other") site on the first enzyme participating in the pathway.

feedback inhibition

Match the following stages of aerobic cellular respiration to where it takes place within the cell. (oxidative phosphorylation)

inner membrane of the mitochondria

A(n) metabolic pathway is a sequence or series of linked chemical reactions carried out in a cell in order to breakdown or synthesize molecules.

metabolic

Match the following stages of aerobic cellular respiration to where it takes place within the cell. (citric acid cycle)

mitochondrial matrix

Match the following stages of aerobic cellular respiration to where it takes place within the cell. (pyruvate oxidation)

mitochondrial matrix

[ Select ] is the division of the genetic material in the nucleus and produces two daughter nuclei. [ Select ] is the division of the cytoplasm and produces two daughter cells.

mitosis, cytokinesis

Prometaphase

nuclear envelope is completely fragmented and the spindle fibers can now invade the nuclear area & interact with sister chromatids

When an atom (or molecule) loses an electron (or in biology a hydrogen atom with an electron) it is said to have been catabolized .

oxidized

The light reactions take place in the [ Select ] while the Calvin Cycle reactions take place in the [ Select ].

thylakoid membrane, stroma

What is the net gain of ATP per glucose molecule going through pyruvate oxidation?

0

What is the net gain of ATP per glucose molecule going through the citric acid cycle?

2

endergonic reaction

B

The equation below represents the energy of a given system. Which variable in the equation represents the free energy (that is, useable energy or the energy available to do work)? H=G+TS

G

Which of the following is NOT a chemical product of the light reactions

G3P

If you measured the amount of DNA in cells you would find that the quantity of DNA in the cells doubled

between the G1 and G2 phases of interphase

The pictured equation is the overall equation for photosynthesis. This is an endergonic redox reaction. In this reaction, [ Select ] is reduced while [ Select ] is oxidized.

carbon dioxide, water

Prophase

chromatids condense into highly compact structures that are readily visible by light microscopy

Telophase

chromosomes reach their respective poles, decondense, & the nuclear membrane reforms

metaphase

pairs of sister chromatids are aligned along a plane halfway between the poles of the cell and appear to be organized in a single row

anaphase

the connection between sister chromatids are broken and the sisters separate and move along the spindle fibers toward opposite ends
