The Nervous System II: Ion Channels 1. List four neurotransmitters that bind to ion channels‚ these neurotransmitters are called __directly____-acting neurotransmitters. a. ACh b. glutamate c. GABA d. Glycine 2. a. The binding of ACh opens ion channels in the dendrites or cell body that permits both _sodium______ and _potassium____ to move through them. b. Which ion would move into the cell? _sodium____out of the cell? _potassium_____________ c. Which ion has the greatest electrochemical

Objective: To investigate how pH affects the rate of protein digestion Hypothesis: I predict that since pepsin breaks down the material the quickest at a pH of 2 in the stomach‚ test tubes #3 will reduce the greatest because it has pepsin to further break down the egg. Whereas the other test tubes will have a smaller reduction. I think test tube #2 will have the second largest reduction rate and then #6 because they all will have a greater rate at breaking down the material‚ Then‚ I predict the

It makes sense to think that quick‚ post-workout protein intake might boost recovery and promote higher performances on subsequent days of training. Indeed‚ some research has suggested that protein intake can help athletes adapt to their workouts more effectively. However‚ such studies have been flawed methodologically‚ and a new investigation reveals that combining protein with carbohydrate after workouts is not a superior strategy‚ compared with taking carbs alone. You’ve heard them: The "experts"

Protein powder is bad because it contained a lot of additive‚ sugar and too much protein. Although natural protein provide immune system defense for the body and also contain antioxidant components‚ however‚ that does not mean that protein shake or protein powder has the same function as the natural protein. As time goes by‚ protein powder has become essential for muscle builder to consume. People drink protein shakes or take pills while they are working out or after performing intense exercise.

The first half of module seven discussed protein digestion‚ absorption‚ and metabolism; while the second half focused on pathological stress and kidney disease. Protein digestion occurs in the stomach and small intestine. When a protein reaches the stomach it is denatured by hydrochloric acid. Once the protein is digested pepsin breaks apart the denatured protein into peptides. Peptides move into the small intestine where they encounter an enzyme that digest the peptides into di- or tripeptides‚

Erwin G Communication 17 September‚ 2012 Informative Speech: Whey Protein I. Introduction a. Muscles!! Everyone wants them; guy’s wants big arms and girls wants nice toned bodies. But they aren’t easy to build. Trust me I know. b. Having the opportunity last semester to take a weight training class to try and get more muscle and bulk up I realized I would need some sort of supplement to help me build more muscle. I also learned that it takes a good workout

BENEFITS OF WHEY PROTEIN IN FITNESS For centuries people have been using whey proteins for their beneficial health properties. Whey is derived from milk and is the by product of cheese production. Today it has found its place in nutrition as it offers optimal health and enables good fat burning. It is a low fat‚ low calorie and low carbohydrate food that is placed low on the glycemic index (GI) Scale. Replacing high fat and high calorie meals with this protein will melt the fat away because the

have for protein synthesis? Explanation: The mRNA encodes the amino acid sequence of a protein. During the translation‚ ribosomal RNA combines with other proteins to form a ribosome which amino acids are transported to the ribosome. The combination of mRNA and tRNA converts the mRNA into the amino acid sequence of the protein. Did the two mutations result in a change in the final proteins? If so‚ describe the change. Response/ explanation: A change took place in the final proteins because

question ask is‚ how big is my protein footprint? It also asks‚ does a meat rich diet have a negative impact on our environment? And does it contribute to global warming? With a very small percentage of Americans following a vegetarian diet. I will say that my protein footprint is about the same as the majority of the US population. I understand that a good source of protein can be found in nuts‚ black beans and lentils. However the number one source of protein in a US household‚ comes from
