Summary Introduction

To review:

The reason for the change in different processes during exercise like cardiac output gets double but organs like kidney get 50% less blood flow than normal and skeletal muscles get 10-fold more blood.

Introduction:

During exercise metabolic activity in the skeletal muscle goes way high. It is so because skeletal muscles demand energy in order to fulfill the exercise regime. Thus, blood flow toward the skeletal muscle increase. At the same time, organs like kidney and digestive system get less blood flow as they do not need blood at that time.

Use the Henderson-Hasselbalch equation for a propanoic acid solution (CH₂CH₂CO₂H, pK₁ = 4.874) to calculate the quotient [A-]/[HA] at three different pH values. pH = 4.479 [A-] [HA] [A-] pH = 4.874 [HA] = pH = 5.220 [A-] = [HA]
In order to establish the expiration date of perishable food, growth curve data must be collected. Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16
