1. which of the following rows best describes the relative concentrations of glucose, oxygen, lactic acid (lactate), and carbon dioxide expected from a sample of blood leaving a fatigued muscle that had entered anaerobic cellular respiration?

row\tglucose\toxygen\tlactic acid (lactate)\tcarbon dioxide
a.\thigh\thigh\thigh\tlow
b.\tlow\tlow\tlow\thigh
c.\tlow\tlow\thigh\thigh
d.\thigh\tlow\tlow\thigh

1. aerobic and anaerobic cellular respiration are similar within human cells in that they both

a. release energy from glucose
b. occur in mitochondria
c. require oxygen
d. produce carbon dioxide as a waste product

Explanation:

30.

Step1: Identify stage 2

Stage 2 is Glycolysis.

Step2: Locate Glycolysis

Glycolysis occurs in the cytoplasm (location 4).

Step3: Determine product of Glycolysis

One of the products of Glycolysis is pyruvate. If we assume pyruvate is represented by 9 (as per the instruction to use the numbers given), we have:
Stage: 2
Location: 4
Product: 9

In anaerobic cellular respiration in fatigued muscle, glucose is used up, so its concentration is low. Oxygen is also depleted as anaerobic respiration occurs in low - oxygen conditions. Lactic acid is produced as a by - product, so its concentration is high. Carbon dioxide is also produced, so its concentration is high.

Both aerobic and anaerobic cellular respiration release energy from glucose. Anaerobic respiration occurs in the cytoplasm and does not require oxygen and may not produce carbon dioxide (in the case of lactic - acid fermentation in humans). Aerobic respiration occurs in mitochondria and requires oxygen and produces carbon dioxide.
