Cellular Respiration

If the conversion of pyruvate to lactate or ethanol and CO2 doesn't yield any energy for anaerobic cells, why do they do it? Please keep answer short and precise as possible!!!!!

Cellular respiration

Why is fat a good energy storage molecule in animals? How about Glycogen? Please keep answer short and precise as possible!!!!!

Potential problem...

The oxidation of FADH2 to form FAD: FADH2 (right arrow) FAD + 2H+ + 2e- this has a potential E (prime)=0.219 under biological conditions (pH=7.00) @ 298 K. What is the potential for this process under standard conditions? Please- I need a detailed explanation- not just numbers- I am using this as a study guide for my final

Mitochondria and erythrocytes

Why are mitochondria and erythrocytes red? Please answer this question completely. I need a full understanding of why and how this occurs. Thank you

DNA mRNA

Consider the role of the coenzyme NAD in glucose oxidation. In the process of glycolysis the formation of pyruvate involves the reduction of the coenzyme NAD to NAD.2H. (a) Which other stages of glucose oxidation produce molecules of the reduced coenzyme, NAD.2H? (b) Explain what happens to NAD.2H produced during glycoly

For # 104369 Energy requiring NAD.2H

The oxidation of NAD.2H is an energy -releasing process. Name the energy-requiring process it is coupled to, and explain why this is important for the cell (two or three sentences please) Thank you

What happens to NAD.2H during animal cell production -not for #103139 thankyou

Explain what happens to NAD.2H produced during glycosis 1) in an animal cell respiring aerobically, and 2) in an animal cell respiring respiring anaerobically I have already recieved an answer to this but I need a more simplified answer as I need to answer this in in more than 200 words. Thankyou for your help

Stages of glucose oxidation

In the process of GLYCOSIS (stage 1), the formation of PYRUVATE involves the reduction of the coenzyme NAD to NAD.2H Which other stages of glucose oxidation produce molecules of the reduced coenzyme, NAD.2H I am guessing at stages 2 & 3,

Cell Structure and Function

1. Which of the following organelles is most important in providing energy to the cell? (a) mitochondrion (b) centrosome (c) Nucleus (d) Peroxisome 2. Name the membrane valves that open and close for potassium efflux and sodium influx. (a)ion channels (b)Vacuoles (c)Capillaries 3. What technique can be used to measure cell act

Vocabulary review

The attached vocabulary review is an assignment I would like to have looked over to see if I am matching the terms correctly.

Chemical Equation for an organelle

I have been assigned the cell wall, and cell membrane for a biology project. One aspect of the project is determining the chemical equations for the proceses which occur inside that organelle. i have done research on, and off of the internet and have yet to find any answers. Could someone point me in the right direction, or supp

Cytoplasmic membrane system

Autoradiography depends upon particles emitted from radioactive atoms striking a photographic emulsion that lies on top of the tissue section. When the emulsion is developed, the site where the particle struck the emulsion is developed, the site where the particle struck the emulsion appears as a silver grain, as in figure 8.3a.

Myosin Action Versus Kinesin

Myosin action differs from that of kinesin in that one of the kinesin heads is always in contact with a microtubule, whereas both myosin heads become completely detached from the actin filament. How are these differences correlated with the two types of motor activities in which these proteins engage?
