2. Draw and completely label a cell membrane. [pic] 4. List and briefly discuss the 5 components of cellular membranes. 1. Phospholipids layer- 2 layers ‚ polar and non polar ‚ polar facing the extracellular fluid and cytoplasm 2. Transmembrane proteins-integral membrane proteins are proteins that expand the membrane 3. Interior protein network-peripheral proteins are in the interior side of the membrane 4. Cell surface markers are glycolipids‚ carbohydrates/lipid

The purpose of the experiment was to find out how temperature affects the enzymes activity. For example‚ in Humans if the temperature is too high‚ the individual’s brain enzymes can denature and cause life threatening problems. The opposite can occur as well‚ if the temperature is too low‚ hypothermia can occur and it can be dangerous (Wilson‚ 1996). In the experiment optimal conditions for fungal and bacterial amylase was measured as well. Discovering information‚ such as the optimal temperature

for lipids‚ if in fact a lipid is present‚ the reaction would produce a red/orange color as opposed to no change at all (negative reaction: Stays pink color). This solution of Sudan IV is soluble in lipids‚ but not in water. Benedict’s solution is the test used for reducing sugars or glucose testing. The positive reaction for this test should show a red/brick color after being placed in boiling water for three minutes‚ but if a negative reaction occurs we will get blue color or no change at all

all these different viewpoints‚ as I see personality can be interpreted in various ways. But when it comes to deciding what approach I most identify most with‚ in relation to recognizing individual differences‚ it would have to be within the biological approaches‚ specifically in the focus of the anatomy and physiology.“The physical basis of personality is the brain and it’s tentacles‚ the nerves that each into each corner of the body right down to the tip of the big toe”.

The importance of water in Biological Systems Much of the Earths surface is comprised of water‚ as well as much of biological systems; for instance‚ the human body consists of approximately 70% of water‚ and in other biological organisms this figure could even be 95%. This largely relies on the bonding of water‚ whereby two hydrogen atoms bond to one oxygen atom; hydrogen bonding is the strongest intermolecular force due to its high polarity. Hence‚ what is the biological importance of water? Water

BLO #2 LO #2- Explain how principles that define the Biological Level of Analysis may be demonstrated using theories and/or studies. Introduction Principle 1 Behavior can be innate because it is genetically based. This means that evolution may play a role in behavior. Natural selection makes species differ in behavior due to adaption.

Detection of Biological Molecules Introduction: Without carbon‚ nitrogen‚ hydrogen‚ sulfur‚ oxygen and phosphorus‚ life wouldn’t exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds‚ ionic bonds‚ hydrogen bonds‚ and disulfide bonds. Covalent bonds are especially strong‚ thus‚ are present in monomers‚ the building blocks of life. These monomers combine to make polymers‚ which is a long chain of monomers strung together. Biological molecules

INTRODUCTION Enzymes are a protein serving as a catalyst‚ a chemical agent that changes the rate of the reaction without being consumed by the reaction. Enzymes are proteins made up of long chains of amino acids. These form complex shapes. The enzymes are individuals‚ like the different players on a ball team‚ they have different specific structures and jobs. As one ball player may be very tall and one short‚ the specific different shape of the active site on an enzyme is unique and prepares it
