Answer:
The conversion of ADP to ATP using light energy is the best description of photophosphorylation.
Answer:
The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. 5. The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.
Answer:
A protein with its amino-terminus in the cytoplasm and its carboxy-terminus in the extracellular space. (Ans. A)
Explanation:
Integral membrane protein (IMP) is defined as a membrane protein molecule which is directly attached to the biological membrane known as phospholipid bilayers. All transmembrane proteins are integral membrane protein but not all integral membrane protein are transmembrane proteins.
Integral membrane proteins function as a transporter, receptors, channels, proteins which is responsible for cell adhesion, proteins are also Involved in transduction and build up of energy.
Membrane proteins are class according to their transmembrane domain properties. The N-terminus of an integral membrane protein type I is in the endoplasmic reticulum lumen, where N-terminus of an integral membrane protein type II in the cytoplasm.
Answer:
Well...
Explanation:First of all skin color is determined by how much melanin you have and the one thing that would show more variability in the human population is probably the one that uses less genes, because of how we come from only two genes which makes us different.
This is a question regarding how enzymes increase the rates of reactions. There are choices and the instructions is to check all that apply.
<span>1. They shift the reaction equilibrium towards the products. </span>
<span>2. They increase the concentration of the reactants. </span>
<span>3. They lower the activation energy of the reaction. </span>
<span>4. They decrease the free energy of a reaction. </span>
<span>5. They promote the formation of a transition state.
The correct answers in this question are "they lower the activation energy of the reaction" and "they promote the formation of a transition state". Enzymes do not necessarily shift the the reaction equilibrium to the products, as there are reversible enzymatic reactions that can reverse the pathway back to the substrates. They do not increase the concentration of the reactants as the concentration of the reactants is an independent variable in this process. They do not decrease the free energy of activation as this is a constant in every reaction depending on the substrates and the products.
Enzymes do, however, lower the activation energy of the reaction meaning it will take less energy and effort for the substrates to reach the activation energy to transform it to its transition state then to the products. With this said, enzymes promote the formation of a transition state.
