Question
Chapter 5, Problem 1RQ
Summary Introduction
To determine:
The name of the epidermal cell which is found numerously in the body is:
(a) keratinocytes.
(b) melanocyte.
(c) dendritic cell.
(d) tactile cell.
Expert Solution & Answer
Answer to Problem 1RQ
Solution:
(a) Keratinocytes: The epidermis is rich in keratinocytes.
Explanation of Solution
The epidermis is the outer layer of the body. The keratinocytes are the cells that make up the maximum of the epidermis. These cells reduce water loss from the body and also protect the body from external stress and microbes.

For each of the following problems calculate the following: (Week 6-3 Video with 6-1 and 6-2)
Consult the total catabolic pathways on the last page as a reference for the following questions.
A. How much NADH and FADH2 is produced and fed into the electron transport chain (If any)?
B. How much ATP is made from oxidative phosphorylation (OP), if any? Feed the NADH and FADH2 into the
electron transport chain: 3ATP/NADH, 2ATP/FADH2
C. How much ATP is made by substrate level phosphorylation (SLP)?
D. How much total ATP is made? Add the SLP and OP together.

Show your work using dimensional analysis here:
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. Continue
generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration.
