How many CO2 molecules are produced when three glucose molecules undergo cellular respiration? Explan

Svetlanka [38]

Answer:

<u>18 molecules of </u> $CO_{2}$ <u />

Explanation:

In heterotrophic nutrition, organisms ingest or absorb food made by autotrophs to obtain energy. Planta and other photosynthesizing organisms make sugars via photosynthesis, in a form of (partly) light-dependent biosynthesis.

In mitochondria, they break down sugars through aerobic respiration. For the sugar glucose, this results in the production of carbon dioxide and water along with energy in the form of ATP or adenosine triphosphate.

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen → carbon dioxide+ water+ energy

For 3 molecules of glucose, multiply the number of reactants and products...

(C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP ) x 3

Thus...

3 C6H12O6+ 18 O2 → 18 CO2 + 18 H2O + ≅114 ATP

In corn, red kernel color (R) is dominant to yellow (r) and smooth kernel texture (W) is dominant to wrinkled (w).

Wewaii [24]

Answer:

a. df = 3, chi-square = 1.7333, p value = 7.815

b. we fail to reject null hypothesis

c. it is independent of kernel texture

Explanation:

h0; there is independence

h1; no independence

9:3:3:1 this is the phenotypic ratio

9+3+3+1 = 16

330 red smooth + 97 red wrinkled + 101 yellow smooth + 32 yellow wrinkled

total observed = 560

1. the degree of freedom = n-1

n =4, 4-1 = 3

to get the chi square computation

(O-E)²/E

expected value for red smooth,

9/16 x 560 = 315

chisquare = (330-315)²/315 = 0.7143

expected for red wrinkled

3/16*560 = 105

chisquare = (97-105)²/105 = 0.6095

expected for yellow smooth

3/16*560 = 105

chisquare = (101-105)²/105 = 0.1524

expected for yelow wrinkled

1/16 * 560 = 35

chisquare = (32-35)²/35 = 0.2571

total chisquare = 0.7143+0.6095+0.1524+0.2571

= 1.7333

with probability = 0.05, df = 3, the value of the chi square from x² table = 7.815

1.7333 < 7.815

so we fail to reject the null

c. we conclude that kernel color is independent of kernel texture
