A teacher told his students that the human body makes the equivalent of its own mass in ATP everyday. Explain why at the end of the day only a small proportion of the students' mass was ATP.
ATP is constantly produced and broken down to provide energy. It can't be stored because it is an immediate source of energy throughout the day.

How is ATP synthase created? What is the DNA sequence that codes for it? How can it be related to the transcription/translation process and how enzymes are created?
ATP synthase consists of 2 regions:1. the FO portion is within the membrane. 2. The F1 portion of the ATP synthase is above the membrane, inside the matrix of the...

Why is the first enzyme in TCA cycle called citrate synthase and not citrate synthetase?
Citrate synthase catalyzes the condensation reaction of the acetate residue from acetyl coenzyme A and a molecule of oxaloacetate to form the citrate. However, no ATP is used in this...

How does protein form?
Explain how different bonds contribute into protein hierarchical structure.
Give one example which demonstrates four protein structures.
In the process of translation, a protein is synthesized based on m-DNA. After protein synthesis, posttranslational modifications (covalent chemical and enzymatic modification of the protein, protein splicing, protein folding) begin...

Addition of Phosphate groups to molecules usually requires ATP as source of energy but in glycolysis a phosphate group is added to Glyceraldehyde-3-P without a ATP molecule. How?
Glyceraldehyde-3-P (GAP) is also known as triose phosphate. ATP molecule is not required when adding a phosphate group to Glyceraldehyde-3-P since the triosephosphate isomerase enzyme rapidly transforms the molecules so that...

1. Dicyclohexylcarbodiimide (DCCD) reacts with Asp or Glu residues. What is the effect of DCCD of ATP synthase?
Conserved Asp/Glu residue in ATP synthase provide translocation of protons during the process of ATP synthesis. As a result, reaction between DCCD and conserved Asp/Glu residue will inhibit ATP synthase.

If a poison were only to allow ATP production from glycolysis, what would be the net ATP output?
ATP used = 2ATP produced = 4Net ATP output = 4-2 = 2.I apologise for my tardiness.

If cell was unable to maintain homeostasis and the temperature became too hot how could this prevent ATP synthase from performing its function?
The rise in cellular temperature will denature ATP synthase enzyme, therefore inhibiting it from performing its function.

1.6) Discuss Mitchell’s chemiosmotic hypothesis of ATP generation in mitochondria (discuss the roles of the electron transport chain, proton gradient and ATP synthase complex).
The chemiosmotic hypothesis was proposed by Peter Mitchell. This hypothesis stated that a proton-motive force was responsible for driving the synthesis of ATP. In this hypothesis, protons would be pumped across the inner mitochondrial membrane as electrons went through the electron...
