What is used to measure the rate of reaction of enzymes
Definition

Term
Sucrose is hydrolyzed into glucose and fructose. What kind of reaction is this? is it exergonic or endergonic?
Definition
decomposition; exergonic
Term
Describe the results of increasing concentration of sucrose using benedicts test
Definition
The concentrations increased as follows: 5%, 10%, 20%, 50% and 100% with a control. The color of the tubes went from a greenish-blue (5%), yellowish-green (10%), yellowish-orange (20%), light orange (50%), and dark orange (100%). This indicates that the reaction speed increases as concentration increases, until saturation occurs.
Term
How does temperature have an effect on the rate of a reaction?
Definition
The greater the velocity, the more often molecules will collide, resulting in a faster reaction. Usually a doubling of rate occurs for each 10 C rise in temperature. At some point, the proteins denature and the reaction is stopped.

In lab, 0 C had little precipitate, 23 C showed more precipitate, 37 C showed the most, and 100 C showed none.
Term
How does pH have an effect on the rate of a reaction>
Definition
may modify the shape of proteins and thus affect activity; The optimal pH in lab was at 4.4. Both 1.0 and 8.0 showed little precipitate. 12.0 showed none.
Term
Describe each step in Mitosis.
Definition
1) interphase: nuclear membrane present, chormatin present, centrioles near the center of the cell, chromosomes replicate.

2)Prophase: double chromosomes appear, nuclear membrane disappears, centrioles move toward poles, aster forms around centrioles, spindle forms

3)Metaphase: centriole migration complete, double chromosomes alight on equatorial plane, centromeres divide, double chromosomes separate

4)Anaphase: chromosomes migrate toward poles

5)Telophase: chromosome migration complete, nuclear membrane reappears, cytokinesis occurs

7) Interphase in two daughter cells
Term
How long does each stage in mitosis last?
Definition

prophase- 30 to 60 mins
metaphase- 2 to 6 mins
anaphase- 3 to 15 mins
telophase- 30 to 60 mins
Term
Describe each step in Meiosis
Definition
1)prophase I: diploid number is 46, double stranded chromosomes; synapsis and genes exchanged

2)Metaphase I: migrate to equatorial plane, centromeres do not divide

3)Anaphase I: chromosome reduction, haploid number is 23

4)Telophase I: nuclear membrane cytokinesis

5)Interkinesis: resting stage of DNA replication

6)Prophase II: nuclear membrane disappears and chromosomes appear

7)Metaphase II: equatorial plane, centromeres divide now

8)Anaphase II: migrate toward poles again

9)Telophase II: cytokinesis

10) interphase (with 4 new cells)
Term
Describe spermatogenesis.
Definition
One primary spermatocyte forms two secondary spermatocytes. Each secondary spermatocyte forms 2 spermatids (4 total). These spermatids then each form a mature spermatozoa
Term
Describe oogenesis
Definition
One primary oocyte forms a secondary ocyte and a polar body. The secondary oocyte forms a ootid and one polar body. The polar body forms two more polar bodies. In total, this step has 1 ootid and 3 polar bodies. The ootid then forms a mature egg, the ovum.

What are 4 different passive processes?

Why does brownian movement occur?
Definition
results from the inherent thermal kinetic energy possessed by all substances, living or non-living. This kinetic energy is the cause of diffusion.
Term
What happens to cells placed in hypertonic solution? What is this process called in RBCs?
Definition
cells will lose solvent and shrivel because solute concentration is greater outside the cell than inside. It is called crenation
Term
What happens to cells placed in isotonic solution?
Definition
there will be no net change in the amount of water in cell.
Term
What happens to cells placed in hypotonic solution? What is this called in RBCs?
Definition
Will be net gain of water in the cell, causing a rise in intracellular pressure and the cells will burst because the solute concentration is greater inside the cell than outside. It is called hemolysis.
Term

Definition
hemolysis (RBC ghosts), normal structure, crenation

Definition
In distilled water, was hypotonic so it swelled. In 1.5M sucrose, it was isotonic so no change. In 3.0M sucrose it was hypertonic, so shriveled.
