Summary Introduction

To compare: The structure and functions of a plant cell wall and the extracellular matrix of an animal cell.

Concept introduction: Plants and animals are eukaryotes. They have well organized membrane-bound structures. Cell contains different organelles. Each organelle has its own specific features. The cell wall is the outermost boundary of a plant cell that provides shape and protection to the cell. Animal cells do not have a cell wall but they consist of plasma membrane. The cell synthesizes and secretes a material outside of the cell called extracellular matrix (ECM), which plays a role in the cellular functions and protection.

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
