She notices that the muscle cells are loaded with mitochondria while the macrophages have abundant lysosomes. why is this so?
Kaylis [27]

The muscle cells are loaded with mitochondria to allow large amounts of ATP production while the macrophages have abundant lysosomes to digest the debris and dead organisms like bacteria.

Mitochondria are known as the powerhouse of a cell. This is because most of the ATP production used by various systems in their operation is produced by mitochondria. A chemical called NADH is produced in the mitochondrial matrix through the Krebs cycle. The enzymes embedded in the mitochondrial membrane use this chemical to produce Adenosine Triphosphate, generally known as ATP.

Macrophages are phagocytic white blood cells involved in engulfing and killing pathogens. They are involved in the innate immune response of the body. Lysosomes have specialized enzymes that can kill these pathogens.

Muscle cells need to contract or expand for which they require energy. Thus, they have abundant mitochondria. Whereas, the macrophages have abundant lysosomes to help them kill disease-causing pathogens like a virus or bacteria.

To know more about ATP production in mitochondria, refer to the following link:

Which of the following is a normal process of photosynthesis that could not occur if all reaction centers were inactivated by a
Arturiano [62]

Answer:

A. donation of excited electrons by chlorophyll a to a primary electron acceptor

Explanation:

Photosystems are structures located at the thylakoid membrane that act to harvest energy light in order to convert it into chemical energy. Each photosystem is composed of a light-harvesting complex and a core complex, which in turn is composed of a reaction center. The photosynthetic reaction centers are multi-protein complexes that use light energy to catalyze the electron transfer across the chloroplast thylakoid membrane against a thermodynamic gradient. Moreover, antenna pigments are pigments that capture the energy from photons in order to transfer energy to other pigments in the photosystem (e.g., chlorophyll B and carotenes are antenna pigments, whereas chlorophyll A is the core pigment). Light energy absorbed by antenna pigments in the photosystems is transferred to the reaction center chlorophyll A molecules, thereby exiting electrons in the reaction center. A reaction center consists of two chlorophyll A molecules, which donate electrons to the primary electron acceptor.

IRINA_888 [86]

Carbon dioxide and water are components of air help to trap infrared energy.


Explanation:

The atmosphere of the planet acts in a {very} very similar thanks to a greenhouse. daylight penetrates the clear air and causes the bottom to heat.


The atmosphere then acts as a blanket, keeping the heat of the planet from escaping back to the area. This result is thanks to bound gases within the atmosphere that are superb at gripping and re-radiating the warmth energy before it's lost to the area.

These gases, referred to as "greenhouse gases", embrace greenhouse emission, water vapor, and paraffin.

timurjin [86]
<h2>Importance of Archaea And Bacteria </h2>

Explanation:

  1. Microscopic organisms contain peptidoglycan in the cell divider.
  2. Archaea do not.Explain the explanation that the <em>two kinds, microbes and archaea</em>, have a similar essential structures, yet worked from various synthetic parts.
  3. The archaea and two microbes have cell films and the two of them contain a hydrophobic bit.
  4. The two microorganisms and archaea have a cell divider that ensures them. it is made out of peptidoglycan, though on account of archaea.
  5. The two microscopic organisms and archaea have diverse Ribosomal RNAs (rRNA).
  6. Archea have three RNA polymerases like eukaryotes, yet microorganisms have just one. Archaea have cell dividers that need peptidoglycan and have films that encase lipids with hydrocarbons as opposed to unsaturated fats.
  7. The two microscopic organisms and archaea have diverse Ribosomal RNAs (rRNA).
