Question
Chapter 46.2, Problem 2CYL
Summary Introduction
To explain:
The term thigmotropism.
Introduction:
Tropism in plant displays the movement of a plant in response to environmental stimuli. Plants usually show their maximum growth towards the water and light because they need these sources for their growth. There are four different types of tropism: phototropism (movement in response to light), gravitropism (towards gravity), thigmotropism (toward mechanical stimulation) and hydrotropism (toward the water).

- Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons glycerol . Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2.
