Answer:
In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. In anoxygenic photosynthesis various electron donors are used. Cytochrome b6f and ATP synthase work together to create ATP. This process is called photophosphorylation, which occurs in two different ways.
Explanation:
The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.
The outcome of amino acids if someone overeats protein and calories in general is "the amino acids are stored as fat".
<h3>
What is amino acid?</h3>
Amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life.
You need amino acids for vital processes such as building proteins, hormones, and neurotransmitters.
Amino acids are concentrated in protein-rich foods such as;
- meat,
- fish
- egg
- soybeans, etc
<h3>What are calories?</h3>
Calorie is a unit of energy. This derived from eating energy giving foods.
Excess calories in the body is often store d as fat.
Thus, the outcome of amino acids if someone overeats protein and calories in general is "the amino acids are stored as fat".

Answer:
The voltage-gated potassium channels associated with an action potential provide an example of what type of membrane transport?
A. Simple diffusion.
B.<u> Facilitated diffusion.
</u>
C. Coupled transport.
D. Active transport.
You are studying the entry of a small molecule into red blood cells. You determine the rate of movement across the membrane under a variety of conditions and make the following observations:
i. The molecules can move across the membrane in either direction.
ii. The molecules always move down their concentration gradient.
iii. No energy source is required for the molecules to move across the membrane.
iv. As the difference in concentration across the membrane increases, the rate of transport reaches a maximum.
The mechanism used to get this molecule across the membrane is most likely:
A. simple diffusion.
<u>B. facilitated diffusion.
</u>
C. active transport.
D. There is not enough information to determine a mechanism.
Carrier proteins - exist in two conformations, altered by high affinity binding of the transported molecule. Moves material in either direction, down concentration gradient (facilitated diffusion). EXAMPLE: GluT1 erythrocyte glucose transporter.
Channel proteins - primarily for ion transport. Form an aqueous pore through the lipid bilayer. May be gated. Moves material in either direction, down concentration gradient (facilitated diffusion). EXAMPLES: Voltage-gated sodium channel, erytrhocyte bicarbonate exchange protein.
This might be helpful... because I don't know anything about facilitated diffusion.
This is the case since earthquakes form directly from tectonic plates. It happens when 2 tectonic plates pass by each other and causes fiction from the bumby sides of the plates
