The structure-function pair is which was mismatched from the task above is microtubule; muscle contraction.
The correct answer choice is option a.
What is microtubule mismatched with the function of muscle contraction?The simple reason why microtubule is wrongly mismatched with the function of muscle contraction simply is that the microtubules help to support cell division and protection to cell shape. That being said, cell structures which are found within the cytoplasm are known as cytoplasmic organelles.

Muscle cells contain , a red pigment that stores oxygen needed for muscular activity.
Answer: myoglobin
Explanation:
Muscle cells contain myoglobin, a red pigment that stores oxygen needed for muscular activity.
Myoglobin is a protein found in muscle cells that is responsible for storing and transporting oxygen within the muscle tissue.
It plays a crucial role in providing oxygen to the muscles during periods of high activity or when oxygen supply is limited.
Myoglobin has a unique structure that allows it to bind oxygen molecules.
It contains a heme group, which is similar to the heme found in hemoglobin, the protein responsible for oxygen transport in red blood cells.
The heme group has an iron ion at its core, which binds to oxygen molecules.
When the oxygen concentration is high, such as during rest or low-intensity exercise, myoglobin binds to oxygen, storing it within the muscle cells. This stored oxygen can be readily released when the demand for oxygen increases, such as during intense exercise or when the oxygen supply is reduced, ensuring a constant supply of oxygen to the working muscles.
Thus, the complete sentence is "Muscle cells contain myoglobin, a red pigment that stores oxygen needed for muscular activity".

in earlier chapters your read about receptors in vision. rods play a role in light, and cones play role in light. group of answer choices
At dim light levels, rods are responsible for vision (scotopic vision). At bright light levels, cones become active (photopic vision).
what are rods and cones?
Rods and cones are the two categories of photoreceptors found in the human retina that collect light. Cones are in charge of vision at higher light levels, whereas rods are responsible for vision in low light. Mesopic light levels are those where both are usable.
Rods Lacking in spatial acuity and unable of mediating color, they are capable of scotopic vision (low light levels). The retina's outer edges are densely populated. They are rod-shaped, which helps with nighttime or low light vision. Include the vitamin A-rich pigment rhodopsin, which is important for night vision and makes rods sensitive to light.
Cones are responsible for excellent spatial acuity, photopic vision (higher light levels), and color perception. Most often observed in retina, they are primarily inhabited in the central fovea region. Conical in shape, they aid in the distinction of color and other subtle characteristics.
Long-wavelength sensitive cones (L-cones), middle-wavelength sensitive cones (M-cones), and short-wavelength sensitive cones are the three categories (S-cones). These are made up of violet-colored iodopsin pigment.

The existence of several hexokinase enzymes in various cellular types is one of the main mechanisms that governs the regulation of the hexokinase stage in glycolysis.
In essence, these are proteins that are encoded by various genes yet serve the same purpose in cells. They're referred to as isozymes. Isozymes can differ in their post-translational modifications, enzyme kinetics, expression patterns in various tissues, and ability to bind to various allosteric effectors of glycolysis. This enables the body to exert varying levels of control over the same processes in other parts of the body. There are four significant hexokinase isozymes in vertebrates, and they differ in subcellular locations and kinetics parameters of glycolysis. This enables the body to phosphorylate hexoses differently depending on the various local conditions and physiological function.

which of the following is not a function of calcium? group of answer choices muscle contraction maintenance of blood pressure transmission of nerve impulses stimulating osteoclasts to break down bone
Stimulating osteoclasts to break down bone is not a function of calcium.
Why is calcium important for our body?
Calcium is a mineral that is most frequently linked to strong bones and teeth, but it also plays a critical role in blood clotting, assisting with muscular contraction, and regulating regular heartbeats and nerve activity.
By interacting with regulatory proteins, calcium causes contraction by preventing actin and myosin from interacting in its absence. Different muscles contain two distinct regulation systems.
By raising intracellular calcium in vascular smooth muscle cells, which causes vasoconstriction, and by increasing vascular volume via the renin-angiotensin-aldosterone system, calcium intake may modulate blood pressure (RAAS).
Calcium is the ultimate multitasker in neurons. It aids in the transmission of electrical signals down axons. It causes synaptic terminals to release their neurotransmitter-filled cargo into synapses. Not only that, but it also affects cell development, metabolism, and memory formation.
